Effect of Mesh Density and Element Types on FEA Results
Meshing guidelines are complicated and also depend on what you are
trying to do. Nevertheless the following
series of comparisons illustrate several important concepts on the effect
of mesh density and element type on FEA results.
The analyst should understand these results before trying to
understand anything more complicated.
We have chosen a simple cantilever
beam clamped at one end and loaded at the tip of the other end. Displacements
and peak stresses are then compared for a variety of element types and mesh densities.
