90 ©2023 ANSYS, Inc. Performance Improvement for MPC Contact • Precisely estimating the total number of CEs in the model which reduces Max. Memory about 25% • Skipping calling CE processing routines at the procedure level for small defection. Only once in every load step. • Skipping calling MPC contact element routines for small defection. Only once in each substep. • Limited CEs for rigid constraints for all analyses: Only builds CEs on rigid nodes which connect to other elements or have applied boundary conditions An auto industry model Estimated total number of internal CEs Max.
