New JEDEC industry standard for electronics cooling simulation

By Leave a Comment

Siemens Digital Industries Software announced the establishment of JEP181—a neutral file, XML-based standard from the JEDEC Solid State Technology Association, which is the global leader in standards development for the microelectronics industry. The JEP181 standard simplifies thermal model data sharing between suppliers and end-users in a single file format called ECXML (Electronics Cooling eXtensible Markup Language).

The new standard was created to meet a significant challenge for electronics manufacturers: as increasingly powerful processors allow companies to pack more performance and functionality into their designs, the effective management of heat dissipation and other thermal factors has become essential to the successful design of their next-generation electronics products. Advanced electronics cooling simulation technologies enable the creation of highly accurate thermal models of new product designs. But the absence of a uniform format for the exchange of thermal simulation data throughout supply chains has created unnecessary duplication of effort and the potential introduction of errors into the stream.

Proposed through the JEDEC JC15 committee, the new JEDEC JEP181 standard simplifies thermal model data sharing. With this universal thermal model sharing standard, electronics manufacturers can reduce the time required to simulate and validate their thermal models.

“The JEP181 standard from JEDEC benefits thermal design engineers by providing wider availability of the key data necessary to validate the thermal performance of today’s advanced designs,” stated Ghislain Kaiser, senior director, Intel Corp. “This standardized format will allow more interoperability between engineering teams, leading to substantial time and cost savings by removing design barriers previously common in thermal engineering.”

Thermal model data availability and sharing is one of the key limiting factors in capitalizing on the benefits of thermal simulation throughout the product design process. Countless hours spent on mining product data sheets for thermal information, or re-implementing 2D engineering drawings within thermal simulation tools, can now be replaced by seamlessly importing commercial 3D simulation tools from software suppliers. The JEP181 standard is ideal for emerging technologies and trends such as miniaturization, 2.5D and 3D semiconductor packaging, and 5G technology– all of which demand increased power dissipation density.

“As a leader in industrial software solutions, our contribution to the new JEP181 standard can help drive the digitalization of design data to reduce both time and errors for today’s innovative electronics products,” stated Jean-Claude Ercolanelli senior vice president of Simulation and Test Solutions, Siemens Digital Industries Software. “Enabling a seamless digitalized software flow can radically increase the efficiency and accuracy of thermal simulation and thus, enhance the performance and reliability of digital twin prototypes and manufactured products.”

The latest release of Simcenter 3D 2021

By Leave a Comment

Siemens Digital Industries Software announces the availability of the latest release of Simcenter 3D software, part of the Simcenter portfolio of simulation and test solutions. Simcenter 3D and the Simcenter portfolio are part of the Xcelerator portfolio, Siemens’ integrated portfolio of software, services and application development platform. In the 2021 release, Simcenter 3D continues to further improve its powerful unified and shared engineering platform for all simulation disciplines to help users gain full value of the benefits that simulation provides in terms of cost, speed and impact to innovation. Introducing new enhancements to the AI (Artificial Intelligence) driven user experience, new simulation types as well as refinements in accuracy and enhanced performance speed, Simcenter 3D 2021 can help companies understand true performance of their designs early in their development process.

Evaluate sound performance with auralization: New in Simcenter 3D, pressure results as a function of time (bottom right) can be played as an audio file.

In many applications, product innovation includes the engineering of the advanced material used in them, which is why new materials are being introduced into the market at unprecedented speed. Cracking is a very important consideration for advanced materials, however micro and meso cracking in advanced materials is difficult to model with the finite element method. Simcenter 3D now includes full representative volume element (RVE) separation and 2D and 3D automatic insertion of cracks or cohesive zones in materials. Macro and microstructural models now allow for full mesh separation for a crack to propagate completely through a material.

“Simcenter Multimech allows us to model microstructural cracks and determine how they would affect the overall part,” states Neraj Jain, group leader in simulation and engineering at the DLR Department of Ceramic Composites and Structures. “Using this tool, we can actually see where a crack is developing, how the crack will change our material, and how it will affect the final microstructure of the material.”

New to Simcenter 3D is an auralization post-processing tool that allows users to listen to simulated pressure results to evaluate sound quality. This allows acoustics engineers to actually hear the noise produced from various vibrating components or products as opposed to having to visually evaluate through charts or graphs.

Simulation-driven design can drastically lower the time it takes to bring a product to market. For this reason, Simcenter 3D’s thermal analysis capabilities have been scaled into a vertical solution for mold designers and design engineers. The new NX Mold Cooling product uses Simcenter 3D technology to allow designers to rapidly set up and simulate the thermal performance of an injection mold insert directly in NX as they are designing the mold. This allows for easy and rapid thermal analysis of injection mold designs without having to wait for expert analyst feedback.

Siemens expands Xcelerator portfolio with enhanced Model Based Definition in latest version of NX software

By Leave a Comment

Siemens Digital Industries Software announces the availability of the latest version of NX software, including capabilities that allow companies to use a rules- and knowledge-based approach to Model Based Definition, which builds in best practices and leverages artificial intelligence to dramatically improve productivity. NX Model Based Definition provides a rich set of data that defines a variety of characteristics beyond size and shape to enable a truly comprehensive digital twin. By including non-geometric data within the CAD model, engineers can now produce a complete digital definition of a product in an annotated and organized manner, creating alignment throughout the production process, from design to production through validation.

This image is showing how a PMI can be authored in NX using rules. The NX MBD solution dramatically simplifies the task of authoring PMI and captures key characteristics and knowledge.

“I’ve been in the CAD/PLM game my entire career, over 35 years. Rarely have I been as impressed by a big leap forward as we saw today,” said Tom Gill, Senior Consultant at CIMData, after reviewing the technology. “Siemens continues to innovate and reimagine CAD design in a way that truly looks to the future of design.”

This image is showing the NX PMI Advisor, a fully integrated PMI validation solution that provides notification verifying whether PMI is compliant with industry and company standards. The NX PMI Advisor removes the dependency on highly trained GD&T experts and produces higher quality parts in less time.

A first to the industry, patented technology, NX Model Based Definition answers many of the challenges companies face when digitalizing the design process and transitioning from 2D to 3D. In trying to replicate a drawing-based workflow in the context of 3D CAD design, many companies are ending up with a 3D drawing, which does not have the tools to capture the true business intelligence needed to take advantage of the digital twin and digital thread. Using NX Model Based Definition, designers and engineers can automatically create and reuse data, adding more intelligence to the model, and subsequently leverage the data to inform other products and decisions — moving to a model-based enterprise. Avoiding the manual process of data validation and correction can help enterprises leverage their designs in a new and innovative way, enhancing productivity across the business.

Siemens delivers Artificial Intelligence-powered CAD sketching technology

By Leave a Comment

Siemens Digital Industries Software announced a new solution for capturing concepts in 2D. The NX Sketch software tool enhances sketching in CAD. By changing the underlying technology, users are  able to sketch without pre-defining parameters, design intent, and relationships. Using Artificial Intelligence (AI) to infer relationships on the fly, users can move away from a paper hand sketch and truly create concept designs within NX software. This technology offers flexibility in concept design sketching, and makes it easy to work with imported data, allowing rapid design iteration on legacy data, and to work with tens of thousands of curves within a single sketch. With these latest enhancements to NX, Siemens’ Xcelerator portfolio continues to bring together advanced technology, even within the core of modeling techniques, helping remove the traditional barriers users have experienced to dramatically improve productivity.

Analysis has shown that in an average day or workflow, around 10% of a typical user’s day is spent sketching. In addition, within current design environments most concept sketching is happening outside of the CAD software due to the level of rules and relationships that must be decided on and built into the sketch by the user up front. Often designers in concept design stage do not necessarily know what the final product may be, which requires a sketching environment that is flexible and can evolve with the design. NX offers the flexibility of 2D paper concept design within the 3D CAD environment, as the first in the industry to eliminate upfront constraints on the design. Instead of defining and being limited by constraints such as size or relationships, NX can recognize tangents and other design relationships to adjust on the fly.

“Sketching is at the heart of CAD and is critical to capturing the intent of the digital twin,” said Bob Haubrock, Senior Vice President, Product Engineering Software at Siemens Digital Industries Software. “Even though this is an essential part of the process, sketching hasn’t changed much in the last 40 years. Using technology and innovations from multiple past acquisitions, Siemens is able to take a fresh look at this crucial design step and modernize it in a way that will help our customers achieve significant gains in productivity and innovation.”
