Application of mixed language programming to finite element analysis

FEM is one kind of effective and mature numerical method and most of softwares of FEM are programmed with FORTRAN language. But with the development of software and hardware of computer, customers requirements on the data processing and image processing part of program become higher and higher. Programming with mixed languages of Visual Basic and FORTRAN or C/C++ language and FORTRAN can meet with the requirements. This article did research on main technical problem of mixed language problem of mixed language programming application to FEM, and provides accordingly solution. The solution overcame the FORTRANs intrinsic shortcoming and can satisfy the customers requirements on FEM programming.
