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.
COMSOL Multiphysics
COMSOL Multiphysics gives you a unified environment to simulate designs, devices, and processes across diverse engineering and scientific fields. You can model coupled or multiphysics phenomena by combining any number of physics interfaces into a single model. This flexibility allows you to move beyond single-physics limitations and capture the real-world behavior of your products more accurately.
You can build your own simulation apps using the Application Builder and distribute them to colleagues or clients via COMSOL Compiler or COMSOL Server. This democratizes simulation, allowing team members without modeling expertise to run their own tests. Whether you are working in electromagnetics, structural mechanics, acoustics, or fluid flow, you can manage the entire modeling workflow from geometry creation to physics setup and results visualization within one interface.
