If you have ever simulated a large 3D model in COMSOL Multiphysics and watched your hard drive fill up within minutes, you already know the problem. By default, COMSOL stores the full solution across the entire mesh — every node, every element, every physics variable — for every time step or parameter value in your study. For a fine-mesh with millions of degrees of freedom, that data can easily balloon into tens or even hundreds of gigabytes. The good news is that COMSOL give

From time to time, we receive questions about which functions in COMSOL Multiphysics we appreciate the most. Here are the key features of this commercial tool, sorted from the most popular among consultants collaborating with Simulation Guys.
