Algorithm based on the mesh analysis for computing 2-D magnetostatic fields by the finite difference method
An algorithm based on the mesh analysis for the calculation of 2-D magnetostatic fields by the finite difference method is shown. The idea of fictitious mesh currents is taken from circuit theory. The algorithm is based on computing fictitious mesh fluxes in each cell of the mesh. This algorithm was applied to determine magnetostatic fields and inductances in power transformers. Results were verified with commercial software and with impedance measurements.
