In COMSOL, how one can decide for the proper meshing size?

WebAll of the numerical methods used within COMSOL Multiphysics® discretize the modeling space via a Mesh that serves two purposes. First, this mesh is used to approximate the CAD geometry. Second, the approximate solution to the problem is solved at discrete points in space defined by this mesh. As this mesh is refined, the solution will tend to ... WebThe simplest definition of mesh or grid is the process of dividing the domain in small sub domains. We can imagine the smallest sub domain as equivalent to a control volume used in the derivations of fluid dynamics and heat transfer equations. The small sub domains are referred as cells or elements in CFD community. physical therapy receipt
