COMSOL Multiphysics and the LiveLink for MATLAB

Interactive multiphysics modeling and simulation


  • Predefined physics and user-defined equations
  • High-performance numerical algorithms
  • Powerful postprocessing capabilities
  • Application-specific add-ons for chemical engineering, heat transfer,  structural mechanics, electromagnetics, fluid flow and more
  • Bidirectional interface with MATLAB ® via the LiveLink™ for MATLAB
  • Models can be enriched with custom user interfaces and compiled into stand-alone applications


The COMSOL Multiphysics® simulation environment facilitates all steps in the modeling process—defining your geometry, specifying physics, meshing, solving, and then postprocessing the results. Optionally, by adding a tailored graphical user interface to your model, you can turn it into an application that is usable by anyone, regardless of modeling experience. Those applications can be deployed over the web using COMSOL Server, or compiled with COMSOL Compiler to run stand-alone. Model setup is quick, due to a number of predefined modeling interfaces for applications ranging from fluid flow and heat transfer to structural mechanics and electromagnetic analyses. Material properties, source terms, and boundary conditions can all be arbitrary functions of the dependent variables.

Predefined multiphysics-application templates solve many common problem types. You have the option of choosing different physics from the Multiphysics menu and defining the interdependencies yourself. Or you can specify your own partial differential equations (PDEs) and couple them with other equations and physics. 

COMSOL Multiphysics is integrated with MATLAB via the LiveLink for MATLAB, which lets you generate a MATLAB file version of a simulation built with COMSOL Multiphysics. You can modify the model MATLAB file, extend it with MATLAB code, and run it from MATLAB.
