Different quality measures are used to quantify the quality of elements. Mesh Element QualityĪ mesh element of high quality is one that is as isotropic as possible for example, a hexahedral cube-shaped element. Let’s go over these factors in more detail. Sufficient resolution for the desired accuracy.The COMSOL Multiphysics® software performs automatic checks that prevent the violation of these two rules (unless specified).Ī good CFD mesh should also aim for the following three factors, which are often in conflict: Most modern meshing tools either contain automatic checks or provide tools to easily detect and remedy transgressions. No void regions in the computational domain.In this blog post, we describe the factors of a quality mesh and how to prepare a fluid flow model geometry for meshing. It is therefore worthwhile to invest time and thought into creating the mesh when solving a CFD problem.
A good mesh facilitates convergence, reduces memory requirements, and results in accurate solutions. The quality of a computational fluid dynamics (CFD) model is often determined by the quality of the mesh used to solve the problem.
