METHOD AND SYSTEM FOR SOLVING BEM USING PRECONDITIONED GMRES ALGORITHM

摘要

PURPOSE: A method and a system for solving numeric analysis using a GMRES algorithm are provided to maintain the linearity independence of a basis vector generated in a Gram-Schmidt scheme and to reduce the number of reorthogonalization. CONSTITUTION: An input unit(110) receives an input value for numerical analysis using a GMRES(Generalized Minimal Residual method) algorithm. An interpretive method analysis unit(120) analyzes a type of a numerical analysis based on the input value. An equation setting unit(130) applies a boundary element method according to an analysis result. An equation operation unit(140) applies the GMRES algorithm.
