Overview
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.
Diabatix ColdStream
ColdStream is a cloud-native platform that transforms how you approach thermal management and cooling challenges. Instead of manually iterating through designs, you define your boundary conditions and let the generative design engine create optimized cooling structures for you. It handles everything from liquid cooling and heat sinks to complex battery thermal management systems, ensuring your components stay within safe temperature limits while minimizing pressure drop and material use.
You can move from initial concept to a high-fidelity, manufacturable design in a fraction of the time required by traditional CFD methods. The platform is built for engineers in industries like automotive, aerospace, and electronics who need to solve extreme heat dissipation problems. By moving your thermal simulation to the cloud, you eliminate the need for expensive local hardware while gaining access to powerful optimization algorithms that explore design possibilities you might never have considered manually.
