Volume Graphics releases new generation of CT Software

By Leave a Comment

–Volume Graphics announced the latest generation of its software solutions for non-destructive quality assurance with industrial computed tomography (CT): Version 3.3 of VGSTUDIO MAX, VGSTUDIO, VGMETROLOGY, and VGinLINE.

VGSTUDIO MAX software is used for the analysis and visualization of industrial computed tomography (CT) data and covers all requirements related to metrology, defect detection and assessment, material properties, and simulation.

Using the new version, customers can determine the surfaces of multi-material components, export measurement and analysis results to store them centrally in quality-management software, automate inspection processes more flexibly based on text recognition, and translate real CT data into volume meshes for simulation.

To further support their customers, Volume Graphics has also added a Technical Consulting unit that provides professional consulting and evaluation services.

“With version 3.3 of our software solutions, we are once again laying the foundation for customers to make their processes smarter,” says Christof Reinhart, CEO and co-founder of Volume Graphics GmbH.

“For example, using the new data export, metrology data derived with the tremendous measurement capabilities of our software can be seamlessly shared with QA systems, where the values can then be combined and checked over time. More than ever before, this new feature enables customers to better integrate leading-edge CT technology into their existing software landscape. The new export feature is based on the native support of the widely used Q-DAS format, which makes using results in third-party statistical or analysis software especially easy.”

An overview of the innovations in VGSTUDIO MAX 3.3: Multi-material surface determination

–A new mode of the local-adaptive-surface determination enables the simultaneous determination of the surfaces of each material within a volume in one go
–This significantly simplifies the geometric dimensioning and tolerancing of multi-material objects, e.g., the position of metal pins of a connector relative to the plastic housing
–The new mode also facilitates segmentation of multi-material objects

Support of native data export in Q-DAS format

–There is now native support for data export in Q-DAS format for both VGSTUDIO MAX and the VGMETROLOGY metrology solution, as well as the VGinLINE solution for automated CT inspection
–Companies that still work with traditional measurement systems can switch to this comprehensive CT measurement technology without encountering software hurdles or having to forego their established processes for further statistical evaluation
–Export of detailed, CT-based measurement and analysis results (coordinate measurement, nominal/actual comparison, wall thickness analysis, porosity/inclusion analysis, fiber composite material analysis) is now enabled in the common Q-DAS data exchange format

OCR-based automation
–New optical character recognition (OCR) allows customers to read out text in CT scans, such as object identifiers, and store the recognized text in their meta information
–In automated inspection workflows, cavity markers in CT scans of injection molded or cast components can be recognized and the right reference object or the appropriate analysis in VGinLINE jobs can then be selected depending on the respective cavity
–At the same time, the recognized text improves the traceability of the results, since the information about the cavities can be included in the reports

 

Volume meshing for simulations
–With the new Volume Meshing Module, users can create accurate and high-quality tetrahedral volume meshes from their CT scans for use in mechanical, fluid, thermal, electrical, and other FEM simulations in third party software
–This is based directly on the subvoxel-accurate surface determination for scanned parts or material samples consisting of one or more materials
–The individual components of multi-material objects are translated into volume meshes with congruent tetrahedron faces and shared nodes at material interfaces
–The complete workflow from CT scan to volume mesh is covered
–Generated volume meshes can be exported in common .pat and .inp file formats
–Each cell of the generated volume mesh can be loaded with additional information required for simulation, such as fiber orientations, fiber volume fractions, porosity volume fractions, or gray values

Backed by 20 years’ experience in industrial CT, the new Technical Consulting unit analyzes the specific requirements of each customer’s application(s), creates optimal software configurations and general CT hardware specifications, and offers complete evaluations as a contract service

Virtalis uses HOOPS Exchange to create rich data

By Leave a Comment

Tech Soft 3D, a leading provider of software development toolkits to engineering software companies, announced that Virtalis is using HOOPS Exchange to create rich data sets that fuel enterprise data models that serve as the visualization backbone for multiple types of applications across the enterprise. Virtalis is a pioneer in the AR/VR industry and provider of immersive visualization solutions that cover the full lifecycle of the product, from conceptual design to distribution.

Visionary Render is Virtalis’ flagship platform for importing and visualizing large datasets from a range of sources, while maintaining all the geometry, naming hierarchies, metadata, and product & manufacturing information (PMI). Virtalis is focused on supporting industrial applications and manufacturers creating large complex products for aerospace, defense and automotive, as well as construction, geoscience, consumer goods, and more. Accurately supporting the formats used in this wide range of industries is critical because companies need to visualize large amounts of data from diverse sources. Being able to review the data in an immersive environment on a one-to-one scale, rather than seeing a 2D view of a 3D object is effective for communicating to people who aren’t skilled in CAD.

“When we import CAD data with HOOPS Exchange, we get the data that we expect,” said Barry King, Product Owner at Virtalis. “Our customers expect to see reliable data when they’re making important decisions based on visualizations and having reliable and dependable data is one of the most important things for them. What’s great about HOOPS is that it supports almost all the formats, including VRML. Our customers have legacy data, and we rely on the fact that HOOPS Exchange supports those formats. Often our customers will challenge us with data and we can say, ‘no problem.’ We can support this wide variety of formats because we have HOOPS behind us.”

Virtalis goes beyond visualizing CAD data from an external view by immersing users in the environment where the model may live, allowing them to experience the product.

“We’re looking at products in the context of where they sit,” said Gavin England, Product Marketing Manager at Virtalis. “We could be looking at a product installed inside a factory, or a building structure coming from building information modeling (BIM) data. In addition to the core formats, being able to bring in data like Revit is key as well.”

HOOPS Exchange provides access to a broad range of data including B-Rep geometry, metadata, PMI, model tree, views, persistent IDs, styles, construction geometry, visualization and more – all without depending on any CAD system. This wide-ranging access proved to be an important element in Virtalis’ decision-making process.

“When we initially were getting to grips and integrating it, Tech Soft 3D was really responsive and collaborated with us to get the results that we needed,” said King. “When we communicate an issue, we always get it fixed in the next release, and the releases come out steadily and reliably.” That’s very important and a real benefit for us. Whether they’re working with engineering or science data, a lot of customers are learning how much time and money they can save by leveraging immersive visualization and not having to build physical prototypes. This helps them make better business decisions – and Tech Soft 3D plays a critical role in supporting those workflows.”

COMSOL Multiphysics includes tools to support 5G, IoT design

By Leave a Comment

COMSOL announced the latest advances in its COMSOL Multiphysics software to support microwave and RF engineers working on 5G, IoT, automotive radars and satellite communications. With these tools, designers can model different PCB materials and study how they affect the performance of microwave and millimeter wave circuits. Several of the application examples to guide designers will be introduced at the International Microwave Symposium (IMS) 2019.

“We are particularly excited to demonstrate how to set up and run a simulation to design and evaluate a Grounded Coplanar Waveguide (GCPW) line,” said Jiyoun Munn, technical product manager of the RF Module at COMSOL. “Connectors and low loss materials are the key components across all electronic devices and systems. Their reliability is critical in circuits that transmit and receive information.”

The use of simulation to achieve low insertion loss and reliable circuit performance in a design, requires choosing accurate material properties such as relative dielectric constant and loss tangent, while also considering surface roughness effects in the computer model.
“As the frequency increases, maintaining the impedance become more complex, as small quirks arising from the geometry or selected materials can be magnified,” explains Bill Rosas, Cofounder of Signal Microwave. “Simulation allows us to ensure that these critical pieces of RF infrastructure are optimized for 5G communications.”

Designing components ready for 5G, IoT, automotive radars and satellite communications will require multiphysics modeling. Using COMSOL Multiphysics microwave and RF designers can couple electromagnetic simulations with heat transfer, structural mechanics, fluid flow, and other physical phenomena, allowing them to represent coupled physics effects as they would occur in the real world. That means being able to accurately investigate designs and fully benefit from the virtual prototyping capabilities multiphysics simulation offers.
