The domin ting computing work of el stic structure st tic buckling n ly sis w s p r llelized, nd the p r llel solver w s implemented in Fortr n90 nd MPI. Moreover , the - , p r llel solver w s embedded into the origin l solution sequence s sub module nd could be c lled directly . For convenient use, the development for friendly interf ce w s implemented. The integr ted softw re, w hich includes seri l pre- nd postprocessors with p r llel
