摘　　要：Parallel computation of FEM under systolic distributed network is a impor-tallt direction of FEM parallel computation. A program designing method and itsimplementation for FEM parallel analysis under network based on PVM is pre-sented. Substructure parallel analysis method with multi-front parallel processingis adopted in FEM parallel computation, the interface equations are solved withPreconditioned Conjugate Gradient (PCG) method. The implementation of thisdesigning method is easy. Example shows the designing method can obtain higherspeedup ratio.Parallel computation of FEM under systolic distributed network is a impor-tallt direction of FEM parallel computation.
