FEA　is　a　key　product　development　tool,　and　remote　FEA　(Finite　Element　Analysis)　services　via　internet　are　an　effective　and　economical　way　to　popularizing　FEA　technology　for　different-sized　manufacturing　enterprises.　For　FEA　Grid　portal,　modeling　technologies　of　FEA　grid　services　and　Grid　information　management　structure　are　presented　in　this　paper.　For　modeling　technologies　of　FEA　grid　service,　workflow　of　FEA　automatic　analysis　job,　models　of　FEA　grid　service　and　data　management　are　described.　WSRF　(Web　Service　Resource　Framework)　based　Grid　information　management　structure　is　presented,　and　an　application　scenario　of　remote　FEA　service　is　demonstrated　by　taking　FEA　parametric　optimization　job　as　example.　The　research　results　in　this　paper　provide　the　basis　for　developing　FEA　Grid　portal.
