Replace FEM overview

Use Replace FEM to substitute a new or existing FEM file for the file currently associated with the displayed Simulation file.

Typically, you use Replace FEM when you have defined a Simulation file with complex boundary conditions, such as field-based or expression-based loads. You can use Save As to create a copy of the Simulation file, and then replace the FEM file with a FEM file defined for another model.

The software preserves all defined solutions, solution processes, loads, constraints, and solver-specific solution objects. As far as possible, the software attempts to map boundary conditions to the replacement FEM. You can then edit the remaining defined boundary conditions to attach them to the replacement FEM's geometry or mesh as necessary.

model_A_sim model_A_fem model_A_i model_A	model_B_fem model_B_i model_B

Two CAE models, model_A (left) and model_B (right). The source simulation file (model_A_sim) contains complex loads and boundary conditions that you want to reuse in model_B.

model_A_sim model_B_fem model_B_i model_B

With model_A_sim displayed, choose Replace FEM and select model_B_fem. You can now apply the loads defined for model_A to the mesh defined for model_B.

Where do I find it?

With the Simulation file displayed, in the Simulation Navigator, right-click the Simulation node and choose Replace FEM.
