Finite element analysis by transputer

This paper describes a speed up of finite element analysis by a parallel computer using transputer. As a solver suited for parallel computers, skyline method by Cholesky decomposition in inner product form is presented. This algorithm uses row wise Cholesky decomposition and its parallelism can be extracted easily. In the three dimensional structural analysis, concurrent processing of three rows and columns is shown to be effective. Using this solver, elastic-plastic analyses have been carried out and the computational speed by 4 transputers was about 10 to 20 times faster than by EWS. Furthermore, this solver is one of the direct methods, independent of the number of processors or the architecture of parallel computers and a promising speed up by both vector and parallel processing is possible.
