Abstract: This paper discusses the implementation of a parallel program that performs a two dimensional rigid frame analysis on a NCUBE/7 hypercube multicomputer. The program was written in C and makes use of the Ghost node I/O system. The rigid frame analysis program was adapted from a FORTRAN program published by D. L. Logan in a 1986 text book on the finite element method. The program has demonstrated significant improvement in the computational time required even for small structural systems with less than 100 degrees of freedom. The input to the program was modified and modeled after that of a STRUDL input file.
