基于Microsoft.NET的有限元应用网格门户研究

为了实现Microsoft．NET平台下分布式有限元分析资源共享和集成，在对有限元应用网格门户基本要求分析的基础上，提出了三层结构的有限元应用网格门户总体框架，并详细分析了其功能和结构。为了实现该框架模型，给出了基于用户角色和身份验证可信度的网格门户安全访问机制，分析了网格作业管理器工作原理并提出了实现方案，给出了基于OGSI．NET网格服务容器实现ANSYS有限元网格服务的方法。网格门户框架和实现方法研究的成果为有限元网格门户的深入研究提供了基础，将促进下一步的网格门户开发。

Research on microsoft. NET based grid portal for finite element analysis application

To implement distributed resources sharing and integration of Finite Element Analysis(FEA) application based on Microsoft.NET platform,the framework of threelayered grid portal for FEA application was put forward based on analyzing fundamental requirements from grid portal,and analysis on the portal functions and architecture was conducted in detail.To implement the framework,security access mechanism of grid portal based on user role and trust level of identity authentication was provided,and working principles of grid job manager were analyzed and corresponding implementation scheme was offered.An approach to implement FEA grid service was suggested based on ANSYS analysis software and OGSI.NET grid service container.Research on grid portal framework and its implementation has proposed further research trend on grid portal for FEA application and promoted its further development.
