INDUCTANCE COMPUTATION USING SCALAR BEM

摘要

The procedure based on scalar magnetic potential introduces cuts such that the multiply connectedrndomain is transformed into a simply connected one. Each cut introduces an additional term containingrnthe "hall" current multiplied by the solid angle under which the cut is seen. The kernel singularitiesrnare easily solved by analytical evaluation of the matrix entries. The surface integral is transformed inrnline integral along the surface boundary when the magnetic flux has to be calculated. In order tornobtain the inductivities, the computing of the fluxes of the cuts needs a special treatment because of thernkernel singularity.
