  • Abstract
    Simple and efficient numerical procedures using singularity cancellation methods are presented for evaluating singular and near-singular potential integrals. Four different transformations are compared and the advantages of the radial-angular transform are demonstrated. A method is then described for optimizing this integration scheme.
