A simple approach to the numerical simulation with trimmed CAD surfaces
It offers an easy-to-implement solution for handling trimmed surfaces in existing simulation software, though the improvement is incremental.
The paper presents a simple method for numerical simulation with trimmed CAD surfaces, verified on structural mechanics examples and demonstrated in FEM and BEM applications.
In this work a novel method for the analysis with trimmed CAD surfaces is presented. The method involves an additional mapping step and the attraction stems from its sim- plicity and ease of implementation into existing Finite Element (FEM) or Boundary Element (BEM) software. The method is first verified with classical test examples in structural mechanics. Then two practical applications are presented one using the FEM, the other the BEM, that show the applicability of the method.
