|Title||PARALLEL FINITE ELEMENT METHOD CALCULATION SYSTEM|
There is a problem that as the method of loosening very large scale structure problem, the DDM , pre-processed with the region splitting method ( DDM ), and Neumann BDD method, and the parallel CG method are known. However it emits and the injury does not save. Therefore the calculation time is lengthened. The invention solves the problem.
The invention relates to the parallel infinite element method calculation system in which free 100 loosens very large scale structure problem described in the above. And the means sectioned, the means distributed to the part, the set means the stiffness matrix, the means setting up the part whole domain overlapping motion, the means performing the early stage setting of the pre-processed project CG method of the total jar conduction, and the means doing the repeated calculation of the pre-processed project CG method of the total jar conduction and the means outputting the displacement injury is included. As to the means distributed to the part, each processor manages the partial area.
The vector space, the common region project gradient method, and the free, is the positive definite symmetry linear transformation internal the permission displacement field, and the finite dimension.
