As an example, large assemblies or overly complicated geometry can result in large numbers of elements being created and will increase setup and analysis time. There are several guidelines to consider during the CAD model preparation phase that can simplify the FEA process and help to control the size of the FEA models. The objectives of this module are: - Learn considerations of when to simplify geometry and what can be simplified - Learn what to preserve in a model - Learn about combining geometry - Learn about excluding geometry / use of boundary conditions - Learn about using symmetry and anti-symmetry - Learn when to split geometry
