摘要：

This work presents a robust bidimensional finite element method (FEM) to disassembly and assembly only modified elements in global matrix. It integrates biconjugate gradient stabilized iterative method and incomplete LU threshold preconditioner to solve linear systems for nondiagonal sparse matrixes, decreasing FEM runtime around 70% in some applications.
