How to Automatically Remove Small Details in Your Model Geometry

July 12, 2019

Have you ever wished for an automatic way to remove small details in your model geometry that are causing an unnecessarily fine mesh or a poor mesh quality? Enter the Remove Details operation.

Is Meshing Run in Parallel in COMSOL Multiphysics®?

May 3, 2019

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.

How to Use Interpolated Material Data to Model Irregular Geometries

March 20, 2018

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.

How to Build Geometries from Elevation Data to Model Irregular Shapes

December 19, 2017

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.

Modeling Irregular Shapes: How to Import Curve Data and Loft a Solid

September 20, 2017

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.

How to Inspect Your Mesh in COMSOL Multiphysics®

May 12, 2017

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.

How to Use Topology Optimization Results as Model Geometries

February 1, 2017

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.

Improved Functionality and Tips for Importing STL and NASTRAN® Files

September 14, 2016

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.
