To optimize your modeling processes, there are a number of built-in materials available for you to use in the COMSOL Multiphysics® software. Along with these materials are features and functionality that allow you to efficiently assign materials to geometric entities in your model. These tools help expedite the process of assigning materials, specifying material properties, and even comparing the impact of different materials on your simulation results. Here, we’ll highlight three tutorial videos that showcase how to use such tools.

STL files originating from 3D scan sources and meshes in the NASTRAN® file format are often used as bases for geometries. However, performing simulations on these realistic objects can be challenging, particularly when preparing the geometry. The COMSOL Multiphysics® software contains features for dealing with these files. Learn how to utilize this functionality as well as how to achieve good results when importing STL and NASTRAN® files.
