FEM Mode
FEM mode enables you to create a mathematical model based on a Creo Parametric part or assembly, then analyze that part using any of several third-party finite element solvers such as NASTRAN, ANSYS, and so forth. The activities you perform in FEM mode are similar to those you perform in native mode. You complete such tasks as adding modeling entities such as loads, constraints, and so forth as well as defining analyses. However, unlike native mode, you must explicitly create a mesh for your model instead of having Creo Simulate perform this step automatically at run time. You also need to explicitly output your model to one of the supported FEA solvers, which analyzes the structural or thermal integrity of the model based on how you set up the simulation.
