概要

論文の詳細を見る
The development of an expert system for two-dimensional elastostatic BEM analysis has been presented in the 1st report. This paper describes a new efficient non-residual type error estimator by using the direct regular method (DRM) and an adaptive meshing method based on the estimated error. Numerical results on the stress concentration problem as well as on the crack problem are given and the good accuracy and convergence of this error estimator are presented. This a posteriori rror estimation and adaptive meshing method are implemented into the expert system for BEM analysis which generates the BEM mesh based on priori error estimation. In the system developed here, the user can estimate the error for the mesh generated by the expert system and refine the mesh automatically to obtain the optimal mesh.
