- Abstract
- This report describes implementation of a sparse direct matrix solver, which was recently developed at DREA, into the VAST finite element program for linear and nonlinear static analyses. The procedures utilized and the new developments required in this implementation are presented in detail. Extensive numerical verifications have bneen conducted using test problems of various sizes. The numerical results indicated that the sparse solver produced identical finite element solutions as the skyline based direct solver, but required significiantly less computation time. These benchmark problems and results are documented in this report.
