Overview
Altair SimLab
Altair SimLab is a multidisciplinary simulation environment designed to help you automate the setup of complex engineering analyses. Instead of manually creating meshes for every part, you can use feature-based modeling to automatically recognize CAD geometry like holes, fillets, and ribs. This allows you to move from raw CAD data to a functional simulation model in minutes rather than hours, ensuring your engineering cycles keep pace with rapid design changes.
You can perform various analyses including structural, thermal, and fluid dynamics within a single interface. The platform is particularly effective for mid-to-large scale manufacturing companies in the automotive, aerospace, and electronics sectors. By capturing and automating repetitive modeling tasks, you reduce human error and free up your engineering team to focus on interpreting results and optimizing product performance.
Cadence Celsius
Cadence Celsius provides you with a unified platform to tackle the most difficult thermal challenges in modern electronic design. You can perform detailed thermal analysis for everything from individual integrated circuits to entire electronic enclosures. By combining finite element analysis with computational fluid dynamics, the software allows you to detect potential hotspots and mechanical stress issues early in your design cycle.
You can seamlessly integrate thermal analysis with your existing electrical power integrity workflows to see how heat affects performance in real-time. This approach helps you reduce the need for expensive physical prototypes and prevents late-stage design failures. It is specifically built for engineering teams working on high-performance computing, automotive electronics, and advanced mobile devices where heat management is critical for product longevity.
