The boundary element method (BEM) is a popular technique to solve engineering problems. We compare the circular arc elements (CAE) discretization to both linear and quadratic discretizations. The main aim of this paper is to determine analytical expressions for the discretization error in 2D BEM for the Laplace equation using CAE discretization. The results are validated by numerical examples. (C) 2010 Elsevier Ltd. All rights reserved.
