Concluding Thoughts on How to Inspect Your Mesh in COMSOL Multiphysics® We have discussed three different ways of inspecting a mesh, which can be used to spot regions with low-quality mesh elements. Now that we know how to find out where the low-quality mesh elements are, we can either...
For commercial software that I install outside of SPACK, I try to automatically load some dependency modules. For instance I installed the physics software COMSOL, which requires GTK+ to display the GUI, therefore I autoload the module:
One of the more common questions we get is: How large of a model can you solve in the COMSOL Multiphysics® software? Although at some level this is a very easy question to answer, it inevitably leads to a longer conversation about numerical methods, modeling strategies and solution algorith...
To easily generate random-looking geometric surfaces, the COMSOL Multiphysics® software provides a powerful set of built-in functions and operators, such as functions for uniform and Gaussian random distributions and a very usefulsumoperator. In this blog post, we show you how to generate a ran...
(FE) method for this purpose. Specifically, the commercial program COMSOL Multiphysics (version 5.2a,www.comsol.com, Stockholm, Sweden) was used to import the setup geometry defined in SolidWorks (version 2018, Dassault Systemes SolidWorks Corporation, France) and to create an extra fine, physics...
As always, you can modify any expression in COMSOL Multiphysics. In this case, we could multiply the in-plane directions of the flow field by a large factor, but it’s even easier to simply set they-component of the arrow plot to zero: ...
