Abstract

Linear system direct solver is commonly used in the general purpose structural finite element systems such as LSNIKE3D7 ANSYS, and MSC/NASTRAN, etc. In this paper, a robust indefinite sparse solver for the linear/nonlinear finite element program LS-NIKE3D is developed and investigated. Two realistic applications are used to show that the new sparse solver is superior to the conventional blocked Cholesky solver of LS-NIKE3D in both CPU time and disk usage.
