A formulation and solution for boundary element analysis of inhomogeneous-nonlinear problem (Q1291831)

The paper presents a 2-D boundary element solution procedure applicable to nonlinear and inhomogeneous problems governed by the Laplace operator. The technique is based on a polynomial spatial interpolation of the nonlinear/inhomogeneous term, whose coefficients are determined through a least squares solution, produced by the integral equation. Boundary and internal computing points are involved and the accuracy is tested with some academic examples.
