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.
SimFlow
SimFlow is a powerful computational fluid dynamics (CFD) platform that brings the capabilities of OpenFOAM to a user-friendly graphical interface. You can handle complex engineering challenges including compressible and incompressible flows, heat transfer, and chemical reactions without writing code. It allows you to import geometry directly from CAD software, create high-quality meshes, and monitor simulations in real-time to ensure accuracy and efficiency.
Whether you are designing automotive components or optimizing HVAC systems, the platform provides the tools to visualize flow patterns and pressure distributions effectively. You can run simulations on your local machine or scale up to high-performance computing clusters for massive datasets. It is designed for engineering professionals and researchers who need the precision of open-source solvers combined with the speed of a modern, intuitive workflow.
