Latest release of Simcenter 3D advances computer-aided engineering and simulation

By Leave a Comment

Siemens announces the latest version of Simcenter 3D, its flagship environment for multi-disciplinary computer-aided engineering (CAE), with new comprehensive solutions across multiple simulation disciplines. Simcenter 3D is an advanced stand-alone CAE application for analysts and discipline experts that works with data from any CAD source. Because it is built on the Siemens NX platform, it also works seamlessly with NX CAD. With more enhancements than any previous release, Simcenter 3D, part of Siemens’s SimcenterTM portfolio of simulation and test solutions for predictive engineering analytics, looks to revolutionize how simulation engineers can help drive design direction in industries such as automotive, aerospace and industrial machinery.

This latest release provides topology optimization solutions that work seamlessly with Convergent Modeling technology to provide comprehensive generative design workflows. These solutions allow for more accurate motion modeling, and more efficient acoustic and structural dynamics simulations. Simcenter 3D now provides expanded support for general purpose nonlinear solutions based on the NX Nastran multi-step nonlinear solver as well as advanced analysis of composites based on LMS Samtech Samcef software. This latest release also delivers several enhancements to improve industry workflows across a wide range of industries, for modeling connections in large assemblies as well as accurate simulation of flexible pipes and hoses.

“Siemens is executing on the Simcenter strategy it announced last year as evidenced by its ongoing investment in new simulation capabilities along with the accelerated integration of CAE technologies acquired over the past several years. The latest release of Simcenter 3D delivers innovative capabilities for topology optimization applied in the context of generative design and also brings together unique hybrid test/analysis technologies that extend the ability to model and simulate system dynamics for complex applications such as high frequency noise and vibration,” said Donald Tolle, practice director, Simulation-Driven Systems Development at CIMdata. “These product enhancements ensure that Simcenter 3D will continue to be a robust, scalable, and multi-disciplinary CAE environment for simulation and analysis specialists.”

Working seamlessly with NX CAD and Convergent Modeling technology, Simcenter 3D now offers generative design solutions for designers and advanced analysts. For the first time, output from a topology optimization process can be utilized directly in the design process, without the need to recreate geometry. Furthermore, engineers can now work directly with scanned data or an optimized shape to conduct more detailed simulations to ensure performance. By using Simcenter 3D along with HEEDS software for design exploration automation, engineers are able to fully explore the design space and generate innovative designs that meet more stringent design requirements.

New with this release, hybrid modeling allows analysts to incorporate test-based data into their simulation models to achieve better accuracy within the simulation. Other enhancements include support for modeling sub-mechanisms within motion assemblies, faster computation time for analytical contact in motion models, and improved performance for interior and exterior acoustics simulation.

Nonlinear simulation in Simcenter 3D is greatly expanded by leveraging enhancements in NX Nastran and integrating capabilities from the LMS Samcef solver. In addition to the already strong capabilities for simulating nonlinear thermo-mechanical behavior in turbomachinery, Simcenter 3D now offers expanded support for general purpose nonlinear simulation with more elements, greater robustness and algorithms for multi-step nonlinear simulation to provide enhanced realism and faster solution times. Additionally, support for curing simulation of composites now allows prediction of residual stresses and spring-back effects.

Several of the enhancements target industry-specific workflows. Simulation engineers in automotive, aerospace, and heavy machinery companies benefit from the integration of universal connections support, which can help to efficiently build large system models with many connections and solve across several solvers. Simcenter 3D also leverages the LMS Samcef solver for simulation of flexible pipes and hoses which are commonly used in a variety of industries.

“Our Simcenter solutions deliver critical capabilities that help our customers engineer innovation into their products,” said Jan Leuridan, senior vice president for Simulation and Test Solutions, Siemens PLM Software. “With our latest release of Simcenter 3D we are able to integrate multiple technologies from different tools all under one platform. Capitalizing on our deep experience in geometry-based CAE as well as our strength in key disciplines such as structural dynamics, acoustics, motion, and nonlinear analysis, we have enhanced Simcenter 3D to enable more streamlined workflows and a broader set of simulations in support of performance engineering.”

A look at Parasolid version 29.1

By Leave a Comment

Parasolid v29.1 from Siemens PLM delivers enhancements to both B-rep modeling and Convergent Modeling technology. B-rep enhancements focus on high-value workflow automation enabling application developers to deliver functionality more effectively. Convergent Modeling enhancements focus on working with imported facet data and the architectural foundations to support fully integrated Convergent Modeling in future where all Parasolid operations will support models containing arbitrary combinations of classic B-rep geometry and facet B-rep geometry.

Modeling

Enhancements have been made to tapering and sweeping to remove potential workflow bottlenecks to deliver successful operations on more complex configurations and provide better diagnostic information when an operation is not possible on a specific configuration:

  • Improved quality surfaces are produced when mitering tangent to faces in a body and provide miter-specific failure information if a body taper fails during a mitering operation.
  • Added support for tapering a body with a negative taper angle.
  • Added option to use a law curve to untwist a twisted sweep along a closed path to ensure alignment at start and end of sweep.
Untwisting a rotation in the path to ensure a successful sweep along the 3D closed path

Siemens and thinkstep jointly Launch Material Management Software

By Leave a Comment

There are so many questions that must be answered by product developers and manufacturers when embarking on new product development. Will it be strong enough? Can it be manufactured cost-effectively? Will it perform as designed? Will it weigh too much? Choosing the right materials is often key to answering many of these questions. With so many materials to choose from–and many more in development–choosing the right one is often a difficult one.

Designers must look at products from a systems level, evaluating each individual part to determine: what are its individual requirements? What is its function? How many are going to be made? What manufacturing methods are going to be used? What material properties are important (mechanical, physical, electrical, aesthetic, process-ability, and cost)? There are resources available to facilitate material selection, such as textbooks, manufacturers’ literature/specs, and online resources.

Automating the material selection process

The result of a joint development project by Siemens and thinkstep might help with the process of choosing materials. Siemens and thinkstep (formerly PE International) today announced a new integrated material management software solution that will help streamline material-driven product design and facilitate manufacturer’s ability to enhance product performance and reliability. The new software will be used to manage the material lifecycle. Siemens and thinkstep expanded their existing partnership agreement to develop this new solution.

The new solution, developed by thinkstep and Siemens’ product lifecycle management (PLM) software business, will help manufacturers improve product performance and reliability by connecting design, engineering, analysis, compliance and manufacturing to a single source of material information. The software, which is part of Siemens’ Teamcenter portfolio, will help reduce errors, rework and recalls that result from the use of inaccurate material data. It will also assist in the re-use of market-tested materials for new products, which is critical in a wide variety of industries.

“Selecting the right materials is critical in order to achieve maximum safety, performance and reliability in our business,” said John Probst, Technical Director, Chip Ganassi Racing with Felix Sabates. “The Teamcenter integrated material management solution opens up new horizons for us in agile materials management that spans design, engineering, simulation and manufacturing processes. In the racing world, where every second counts, we need solutions like this that enable us to create more innovative designs to give our team a competitive advantage.”

“Through our expanded relationship with thinkstep, we’re delivering a competitive advantage to all of our customers through true material management intelligence,” said Eric Sterling, senior vice president, Lifecycle Collaboration Software, Siemens PLM Software. “Products from virtually every industry can fail, and often times the failure results from the inconsistent use of material information. The new Teamcenter integrated material management solution provides a more holistic view of material data for use in all phases of the product lifecycle to help improve quality and reduce development cost. The new solution gives manufacturers the right information at the right time so they can react quickly and realize innovation.”

Material property management systems have evolved significantly to keep pace with the growing demand to capture, store and interrogate material test data. However, these massive volumes of data cannot be considered material intelligence unless the lifecycle of the material data is intrinsically linked with the lifecycle of the product.

Teamcenter integrated material management provides this missing link between material data and true product intelligence. Establishing and maintaining integration between the materials considered for use in a product and the product’s bill-of-materials (BOM) is crucial to delivering successful, innovative products. The Teamcenter integrated material management solution enables the active management of materials throughout the product lifecycle, from design to production to retirement.

Integrated CAM APPS help engineers take designs straight to manufacturing

By 1 Comment

by Barb Schmitz, Senior Editor

There have been many hardware advances on the manufacturing side of product development. Increasingly sophisticated machining technology is becoming more affordable and accessible, and as a result, more and more companies are bringing technology, such as CNC machines, in house. Having the capabilities to create prototypes quickly in house saves significant time to market over the traditional process of outsourcing to machine shops.

Another exciting new technology poised to radically change the landscape for manufacturing forever is the 3D printer, which enables manufacturers, as well as hobbyists and would-be inventors, to quickly create physical prototypes with the push of a button. The prices of these machines and the materials they use have plummeted in recent years, putting the technology in the hands of anyone with an idea and a desire to convert that idea into a reality

New technologies demand new methodologies
As more and more companies are turning to rapid prototyping and manufacturing to cut turnaround time for prototypes and customized one-off parts, the necessity to provide product data in the form of 3D models is increasing.

Three-axis and up NC programming, rapid prototyping, mold design and sheet metal manufacturing now require 3D models that can be referenced to create NC toolpaths, SLA molds and sheetmetal flat patterns with proper bend allowances. These systems require input generated in STL format, which can be easily output from 3D models by saving models in that format.

For companies still creating designs in 2D, problems await. When manufacturers have to “rebuild” 2D drawings in 3D, problems often rear their ugly heads downstream. When mistakes are made translating 2D designs into 3D, the resulting part might not meet its original design requirements. In addition, when drawings are tweaked to work for manufacturing, those original 2D drawings are often not changed, so if referenced later, problems again arise.

Automate CAM with CAD-integrated solutions
CAM is the component that enables engineers to turn their design into a physical part on a CNC machine. With traditional CAM software, the workflow is completely different than the workflow in CAD, making it difficult for engineers to use. Yet, with more and more companies bringing machining capabilities in-house, the ability to use and understand how to generate toolpaths has become more important to engineers.

To make it easier for product designers and engineers to take 3D CAD models straight to manufacturing, many fully CAD-integrated CAM software solutions are now available, typically sold by partners of CAD vendors through their reseller channels.

Single-window integration for CAM means that engineers and designers can launch the CAM app from within their CAD program. When design changes are made, these updates are automatically made in downstream manufacturing applications as well. As a result, accuracy of design data is also maintained because the CAM application creates data by directly referencing the 3D CAD model.

Integrated CAM software also enables designers to assess the manufacturability of products early in the design process. “Integrated CAM helps expedite the manufacturing process by helping engineers and designers gain early insight into the cost, performance and manufacturability of designs,” said Aaron Frankel, marketing director at Siemens PLM. “It also enables easy optimization of designs for maximum manufacturing efficiency by reducing manufacturing steps, improving efficiency of tooling, reducing machining times and maximizing shop floor equipment utilization.”

Mending fences: Integrated CAM facilitates concurrent design
By integrating CAD and CAM, companies seek to solve the traditional disconnect between designers and their manufacturing counterparts. Design engineers have a reputation of simply “lobbing” CAD models over the wall to manufacturing without regard to the efforts required to prepare those models for manufacturing, creating tensions between the two groups that have hampered processes and prohibited truly collaborative design efforts.

EasyFill-Moldex3D
Use integrated mold flow simulation technology, such as EasyFill Moldex3D mold analysis software, to gain insight into the real-world manufacturability of design alternatives.

Traditionally, even though both teams are working on the same design, they use different tools that don’t speak the same language, which requires manufacturing to translate the design data they receive from one language to another. This requires them to import and possibly repair the geometry, which creates delays and increases the likelihood of errors.

ptc-creo-time-to-production
PTC Creo enables faster time-to-production and customer responsiveness.

“The design and manufacturing process is not a one-way street,” said Craig Therrien, a product portfolio manager at SolidWorks. “There are always many iterations back and forth, so every time a designer makes a change, that cycle of importing and exporting begins again. Data translations and conversions add extra steps and introduce potential errors.”

When both teams can work in parallel through an integrated design and manufacturing process, they can react faster to design changes. By using a master model with associativity, users can update their mold design, NC programs, electrodes and setup sheets every time the CAD model changes. Associativity makes design changes go faster and simple changes can be updated automatically— they don’t require reprogramming because they automatically re-adjust. More than one designer can work on the same tool at the same time, and you can start NC programming before the tool design is completed.

PTC-Creo-NC-capabilities
PTC Creo provides users with NC capabilities for mold machining.

“Seamless integration of CAM software into the design process can be a huge help in addressing time-to-market issues,” said Brian Thompson, vice president of Creo Product Management at PTC. “If the manufacturing and design engineers are working with the same data, then early visibility into any manufacturing issues is easy, and the resulting collaboration will allow the team to catch and correct manufacturability issues before they hit the production floor.”

Fully integrated CAM packages enable users to easily automate CAM to help lower costs, increase productivity and speed time to market. Because these solutions work directly with 3D CAD data, there is no need to translate or recreate designs for manufacturing, reducing the chance of errors. Many were also designed to follow more of a CAD-like workflow, making it easier for engineers to learn and use.

While integrated CAM software helps to identify manufacturing issues early in the design process, the benefits continue once products move to production. “Once the design is in production, the benefits of a single, associative data model continue,” said Thompson. “Any changes to the production design are automatically propagated into the manufacturing toolpaths, enabling incredibly quick implementation of product design changes into the manufacturing process.”

An integrated approach to CAM also greatly reduces the traditional disconnect between the two processes—design and manufacturing—by providing an integrated platform that serves the needs of both. “Communication barriers are removed with this approach and processes are smoothed out, reducing cycle times while improving quality,” said Therrien. “It also eliminates the need to import/export/repair model data, improves data accuracy, promotes concurrent design and reduces overall costs.”

HSMWorks
HSMWorks is an integrated CAM solution focused on CNC milling and CNC turning, available exclusively for SolidWorks users but is sold and supported by Autodesk.

Integrated CAM opens doors to new rapid manufacturing technologies
The combination of powerful 3D modeling, CAD-integrated CAM apps and affordable machining technologies, such as 3D printers, has created new opportunities and radically changed the way people think about design. If you can think it and design it, you can now build it.

For design engineers, 3D printing means faster turnarounds on physical prototypes, the ability to make parts that were impossible with traditional manufacturing techniques, and a way to quickly create one-off configurations for truly customized final products.

Using an integrated approach to CAM also will enable users to quickly take advantage of “next-gen” manufacturing equipment, such as new generations of hybrid additive technologies that can both build up and machine metal.

The combination of CAD-integrated CAM software and new advanced rapid manufacturing technologies packs a mean productivity punch. Not only will it help to bridge the gap between design and manufacturing teams, but will also speed time to market for new products while cutting down on errors and the costs associated with them.

Enterprise-wide use of 3D CAD software

By Leave a Comment

Up until 2007, the Ikeda Business Group in Brazil was using a 2D graphics design software to create their mobile equipment, and agricultural and leisure product. Then Helcio Mariano Pinto was hired for coordinating the product design and development for all Ikeda divisions. He was familiar with Solid Edge software and its advanced 3D capabilities. The product was selected for use by all Ikeda employees in part because of its ease of use and processing speed.

“We quickly rolled out the software across the business units,” says Pinto. “With one or two mouse clicks, you can perform simple functions and solve a number of problems.” He said the main goal was to find software with maximum command simplicity. Information quality, project security, design reliability, and project documentation are some of the areas where the company has made gains due to the use of Solid Edge.

In 2010, Ikeda Group migrated to Solid Edge with synchronous technology. Pinto said, “The advantage of synchronous technology is the ability to work with various versions of projects quickly and simultaneously. In addition, users do not have to choose between constraint-driven or history-free modeling. They can re-use a model without programming knowledge, and data from multiple CAD systems can be leveraged immediately. We now work on three or four projects at a time. This affords greater flexibility in pursuing new projects involving agricultural implements, mobile devices, or leisure products. Depending on the complexity of a project, sometimes drafts are reay in one day rather than two weeks.”

Today, the company has six licenses of Solid Edge with synchronous technology and five licenses of Teamcenter Express, which are used for project data management and product lifecycles.

Leader in hydropower equipment seeks world-class advantage

By Leave a Comment

The Flovel Group is a hydropower equipment supplier that provides turnkey solutions for small- and medium-sized hydropower projects. Business units include Flovel Energy Pvt. Ltd., which specializes in the entire range of hydropower equipment and services for design, engineering, manufacturing, installation, and servicing for all heads and outputs covering all types of turbines, and TB Hydro Flovel Valves Pvt. Ltd., which designs and manufactures a variety of inlet, shut-off, regulating, and air valves for turbines.

At one point, Flovel’s management began to look for product development technology that was adept at accelerating the release of highly customized, innovative new products to market, while at the same time being able to ensure the high quality and rigorous accuracy required by its customer base.

To meets its requirements, Flovel selected  products from Siemens PLM Software including Solid Edge, Teamcenter Express, NX, and Femap with NX Nastran. Solid Edge is used for CAD to design complex turbine parts. Flovel based this decision on the software’s ability to handle sophisticated designs, 2D functionality, and sheet metal handling capabilities. Based on the successful use of Solid Edge at Flovel, the company is looking to leverage the product in other areas, including CAE, CAM, and product lifecycle management (PLM).

Using Solid Edge, Flovel has improved its overall design methodology (concept to prototype to product) and cut costs (due to a better understanding of 3D conceptual prototypes). The company cites outstanding ease of use compared to traditional approaches to design, noting that the user-friendly Solid Edge is fostering idea generation and innovation. Flovel also gives Solid Edge praise for superior searching options for making assemblies and points out that the visualization capabilities of Solid Edge measurably accelerates the handling of large assemblies.

Once Solid Edge was in place, Flovel implemented the second step in its product development initiative by adopting Teamcenter Express as its collaborative product data management (cPDM) solution. The goal was to establish a scalable cPDM solution that would facilitate collaboration between all of the key disciplines in the company’s product development operations. The procurement team selected Teamcenter Express for its visualization and collaboration capabilities, strong multi-CAD and multi-site support capabilities, and the ability to streamline the company’s design process. With Teamcenter Express, the company wanted its planning, design, engineering, and production departments to establish a synchronized engineering database with design information that users could easily access, share, and exchange on a secure and controlled basis.

Other goals for Teamcenter Express included establishing drawing number controls and materials codes, identifying the latest versions of their design information, and disseminating information in standard workflow-driven design processes. The company wanted standard, up-to-date information, such as what is contained in product catalogs, quality standards, manuals and plans, to be kept in Teamcenter Express for immediate access. Beyond this, Flovel engaged Teamcenter Express to manage released design information so that it can be leveraged by all of the company’s business units and their manufacturing operations for purposes of improving its CAM and CNC machining processes.

Flovel has extended its design process capabilities by implementing NX which is enabling designers to model difficult surfaces such as runner blades more easily. The company has also implemented Femap with NX Nastran. The intent of this deployment is CAE design optimization.

Currently, Flovel is using Femap with NX Nastran to analyze complex components. The company is performing finite element analysis (FEA) on turbine components for customized applications and operating conditions, as well as using the software to verify designs developed using conventional design tools. In addition, Flovel plans to extend its use of Teamcenter Express to other organizations and integrate the company’s enterprise resource planning (ERP) system into its product development initiative.
