Simulation Tool for Electrical, Mechanical, Fluid Flow, and Chemical Applications. COMSOL Multiphysics® is a general-purpose software platform, based on advanced numerical methods, for modeling and simulating physics-based problems. With COMSOL Multiphysics, you will be able to account for coupled or multiphysics phenomena.

With more than 30 add-on products to choose from, you can further expand the simulation platform with dedicated physics interfaces and tools for electrical, mechanical, fluid flow, and chemical applications. Additional interfacing products connect your COMSOL Multiphysics simulations with technical computing, CAD, and ECAD software.

COMSOL Desktop® for Cross-Disciplinary Product Development
COMSOL Desktop® is a powerful integrated environment designed for cross-disciplinary product development with a unified workflow, regardless of the application area. The add-on modules blend in seamlessly with COMSOL Multiphysics, and the way you operate the software remains the same no matter which add-on products are engaged. The model tree in the Model Builder gives you a full overview of the model and access to all functionality – geometry, mesh, physics settings, boundary conditions, studies, solvers, postprocessing, and visualizations. With COMSOL Multiphysics you can easily extend conventional models for one type of physics into multiphysics models that solve coupled physics phenomena – simultaneously. What's more, accessing this power does not require in-depth knowledge of mathematics or numerical analysis.

COMSOL® Puts the Power of Simulation in Your Hands
With COMSOL Multiphysics® FEA software, you can simulate virtually anything you want, thanks to the underlying flexibility that complements the intuitive and easy-to-use COMSOL Desktop® interface.

For instance, in COMSOL Multiphysics®, you are able to arbitrarily include your own equations that may describe a material property, boundary, source or sink term, or even a unique set of partial differential equations (PDEs). You can then create new physics interfaces from the equations you entered. When creating apps with the Application Builder, you can design your own user interfaces based on your models. These user interfaces can be simplified versions of the model or include only some of the input and output fields you want to give the user of the app access to. COMSOL Multiphysics® also includes a COMSOL® API for use with Java® that adds extra flexibility for connecting your COMSOL Multiphysics® models with other applications.
