一、引言 有限元一体化处理系统FECPS(Finite Element Concertrate Process System),是国家攻关项目《风机、冷冻机、压力容器CAD》中的一个重要部分。我们在充分剖析DDM-FEM软件包和有限元分析(SAP6)程序包的基础上,编写了近五千条DAL和Fortran程序,将前置处理,分析部分,后置处理三大部分成功地融为一体,实现有限元分析处理的一体化,为机械产品的设计提供了有力的工具。 I. INTRODUCTION The finite element integrated processing system FECPS (Finite Element Concertrate Process System) is an important part of the national research project “fan, freezer and pressure vessel CAD”. Based on the full analysis of the DDM-FEM package and the finite element analysis (SAP6) package, we wrote nearly 5,000 DAL and Fortran programs and successfully integrated the preprocessing, analysis and postprocessing into three major parts As one, to achieve the integration of finite element analysis and processing, mechanical products for the design provides a powerful tool.
