This paper compares the hybrid FEM-BEM and FEM-DBCImethods for the solution of open-boundary electrostatic fieldproblems. Both methods couple a differential equation for theinterior problem with an integral equation for the exterior one. Thecomparison shows that FEM-BEM is more accurate than FEM-DBCI butrequires more computing time.
