The research of Key Technology in Pre-processing Module for Finite Element Simulation System of Sheet Forming

摘要

Sheet Metal Forming Fast Analysis system FASTAMP is a commercial finite element simulation system with fully independent copyright. The pre-processing module FASTAMPPRE integrate universal CAD file interface (IGES/VDA) and NASTRAN mesh file interface, is compatible with most popular CAD system; The inner fast surface mesher can mesh most complicated surface model; The function of Point/Line/Surface/Element Edit may be used to repair usual bugs of the surface & element model; The friendly interface and the conveniently operation style make the system easy to use for engineering application. The pre-processing module is very important for the commercialization of finite element simulation system as the key module of the whole system. Many applications show that FASTAMP system can completely meet the request of finite element model building for sheet forming simulation and finally reach commercial level.
