Modeling for Change

摘要

MANY OF YOU WILL HAVE BEEN FACED with a situation where a design is changing rapidly and finite element analysis (FEA) simulation is struggling to keep up. Changes in geometry have a knock-on effect on the mesh, loads and boundary condition strategy. In this scenario, it is difficult to keep FEA in a proactive role in providing design direction, rather than being used in a reactive checking mode. This article reviews some ways in which FEA modeling can anticipate design changes and keep ahead of the curve.
