Error Estimation for Boundary Element Analysis
Publication: Journal of Engineering Mechanics
Volume 115, Issue 9
Abstract
An a posteriori error estimator is developed for boundary element solution of two‐dimensional and axisymmetric potential problems. Two local (element) error norms are formulated for potential and flux which exist in each element. The error norm evaluated for an element is the one for the unknown quantity. The global error norm is found by summing the local error norms. The evaluation of the local error norms for the potential aid flux is based on a projection process of adjacent boundary element solutions. The accuracy and reliability of the proposed error estimator is demonstrated by five problems.
