understand the relation between mesh size and accurate results
In FEA analysis, the number of mesh elements and mesh element size is very important because accuracy of the results depend on it. Even if you can calculate very complex problems of mechanics with FEA which are approaching real world models, FEA is still a numerical approximation method. So more elements you have, the smaller they are and more the results will be accurate. This guide details the factors playing on mesh accuracy using the simple "plate with a hole" tutorial.
