An adaptive algorithm for boundary element method postprocessing

This paper deals with a novel algorithm for drawing contour lines in the postprocessing of the boundary element method calculations for 2D potential problems. The basic idea is to use an adaptive approach to produce a triangular mesh of higher order interpolation. Based on this mesh, the smooth equipotential map can be generated. The advantage is that the CPU time in the postprocessing can be greatly reduced and a grid for drawing the equipotential map has not to be prescribed.
