How to create a good FEA model
Structural analysis with the finite element method can calculate displacements, stresses, durability, vibrations or temperatures. Often, FE modelling begins with the import of CAD geometry into a FEM preprocessor and with the meshing of the geometry. Normally a 3D CAD geometry is available, which you can mesh with tetra elements in one mouseclick. But this may not be the best way. With a fine tetra mesh you probably get reliable results, but the run time increases strongly with the number of elements. It makes sense to use the appropriate mesh type and geometry simplifications for the model. This whitepaper shows you how to mesh a model better and faster. We show the modeling process using the software Apex, and give you tips and tricks what are the important points to check.
