Abstract
The design and implementation of a software system for automatically generating code for finite element analysis are described. Exact symbolic computational techniques are employed to derive strain-displacement matrices and element stiffness matrices. Methods for dealing with the excessive growth of symbolic expressions in practical computations are discussed. Automatic FORTRAN code generation and optimization are described with emphasis on improving the efficiency of the resultant code. The generated code can be used, without modification, with a FORTRAN-based finite element analysis package.
