IMPACT OF DIRICHLET BOUNDARY CONDITION ON CALCULATION RATE AND STABILITY DURING EDDY CURRENT MODELLING USING ELECTRIC SCALAR POTENTIAL


Abstract

Field of presented results are bioelectromagnetic problems. Mathematical description of eddy-currents excited by external, low time-varying magnetic fields coming from the current flowing in the coil, was formulated on the basis of the electric scalar potential. This article shows effect of applies Dirichlet boundary condition to calculation rate and stability. Lots of numerical tests show that it is not always advisable.
