Abstract

This paper is concerned with reanalysis for boundary element systems arid its application in shape optimization. An efficient arid accurate reduction method is proposed for reanalyzing boundary element systems. The new method has several merits. In particular, the reduced system is uncoupled by a Gram-Schmidt orthonormalization procedure. Also, a computation-inexpensive convergence criterion is proposed for the automatic determination of the number of basis vectors required to approximate the solution within a specified level of accuracy. The accuracy and efficiency of the new method are verified by several numerical examples on reanalysis and shape optimization.
