Overview
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.
CONVERGE CFD
CONVERGE CFD changes how you approach fluid dynamics by removing the most time-consuming part of the simulation process: manual meshing. Instead of spending days or weeks refining grids, you can rely on its autonomous meshing capabilities to create the mesh at runtime. This allows you to simulate complex moving geometries and intricate flow patterns with high accuracy and significantly reduced setup time.
You can apply this tool across various industries, from internal combustion engines and gas turbines to pump design and medical devices. The software excels at handling transient simulations where boundaries move or change shape, ensuring your mesh always adapts to the physics of the problem. By automating the grid generation, you can focus your energy on analyzing results and optimizing your designs rather than troubleshooting mesh quality.
