The BIEM is preferable to the Laplace-equation-governed transformation process for a number of reasons: (1) it is not necessary to discretize the entire domain; (2) solutions can be evaluated exactly; (3) derivatives of variables can be evaluated directly without difference schemes; and (4) once the solutions at all the discretized boundary nodes are obtained, at any given point in the domain the solution as well as the partial derivatives can be easily found without remeshing.
