Meshing, an integral part of modeling in COMSOL Multiphysics®, can take up a lot of time and resources. Parallelized meshing speeds things up by distributing the meshing of domains on more cores.

Say you want to build an irregular geometry of a mountain. You can do so by creating a surface of an irregular shape based on elevation data stored formats such as text, image, or DEM files.

You’re meshing your model and a warning or error appears. So, what do you do? One option is to inspect the entities listed in the report to analyze and resolve the meshing issue.

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.

Learn how to model an irregular geometry in COMSOL Multiphysics® by importing material data. The example featured here is for an RF simulation of a human head.

Say you want to model an irregular shape, like a human head. How do you set up the geometry? Here, we go over how to do just that by importing curve data and lofting a solid.

Oftentimes, topology optimization is not the last step in your design process. In fact, you can use the results from a topology optimization study as model geometries for your next analysis.
