CVBEM ERROR REDUCTION USING THE APPROXIMATE BOUNDARY METHOD

The complex variable boundary element method or CVBEM has been shown t o be an effective computational tool for approximately two-dimensional problems involving the Laplace or Poisson equations. In this paper, t he approximate boundary method (ABM) for error reduction in the CVBEM boundary condition approximation is further examined. A norm for evalu ating accuracy and approximation improvement is used to assess the uti lity of the ABM.
