ABSTRACT	This paper describes a heat conduction FEM (Finite Element Method) analysis program for an objective massively parallel computer system with processing elements to be arranged in a two-dimensional mesh based on the computer architecture presented by Harada et al.. Two conditions of parallel processing of the finite element analysis program were found to be effective for the parallel computer in the definite extent of FEM. One was to set dummy elements outside the boundary of the analysis region. The other was to use a two-dimensional array (I,J) corresponding to the grid mesh position of processing elements for the numbering of elements and nodes. Verification of the FEM program for parallel processing was carried out using the parallel computer "Paragon" with 16×21 nodes (processing elements).
