For the parallel analysis, several interfaces have been developed, on one hand, in order to parallelize the existing serial fea codes and make the system practical, some parallel solver library has been integrated into ooparafea ; on the other hand, ooparafea can also integrate self - developed module into its analysis kernel, in fact, it has already integrated parallel cg solver and parallel pcg solver up to now. in webfea, just like other parts in netfeaf, the class hierarchy ( including two dimension fea class library, three dimension fea class library, internet based fem computer aided instruction and so on ) is introduced first, and the control center which integrated httpserver ( used for building internet project web site ) and computingserver ( dealing with different computing tasks ) takes charge of the whole system. netgrawcad is the application of netfeaf in civil engineering, which offers civil engineers a network based works
論文還開發了全新用途的網路服務中心，包括http服務器、計算服務器，以及各種用途的計算客戶端：利用java語言的網路通信、界面處理能力結合集群的密集并行計算能力一起完成特定的計算任務，從而使集群計算與web計算很好的集成在一起； webfea作為一種應用客戶端，配合netfeaf集成系統的各個計算組成部分，可以實現一個比較全面的有限元分析方法的計算機輔助課件；當前基於web的各種應用越來越廣泛，但將基於網路的工程設計與有限元分析系統的面向對象構建其引入有限元分析以及土木工程設計領域還不多，基於netfeaf系統，作者又利用面向對象的方法實現了基於網路的重力式碼頭cad集成系統，以從根本上改變傳統的工程分析設計軟體的運行思路，使網路變成土木工程師的日常工作中心，系統部分成果通過鑒定（文通部鑒定為「國內領先，可以大大提高設計效率，建議在水運行業內盡快推廣使用」 ）推出后的良好試用效果，使面向對象的方法在土木工程分析設計軟體系統研製中的優勢得到進一步驗證。 -
