When you build a mesh in a 3D model, COMSOL shows you only the outside of it. You see the surface triangles, but you do not see what happens inside the domain. Are the elements inside fine enough? Does the boundary layer grow correctly into the volume? Where are the bad elements? The meshed complex structure example. How to inspect the mesh in detail? You can look inside the mesh using a Mesh plot in Results. In this article, you will learn how to do it step by step. Step 1:

A mesh study checks if your mesh is fine enough. You solve the same model on several mesh densities and compare the results. If the answer stops changing, you found a mesh you can trust. You do not need to build this by hand every time. COMSOL lets you start simple and add control step by step. This article shows three levels: the default physics-controlled mesh, an edited physics-induced sequence with a size parameter, and a single scale parameter that drives the whole study
