Abstract :
The three-dimensional boundary-node method has been reformulated without using any integration cells. For evaluation of the influence coefficients, an implicit surface is assumed as a surface boundary and the 3D polar coordinate is employed. Numerical experiments show that, for the Laplace problem, the accuracy of the proposed method is almost the same as that of the boundary-element method with linear elements.
