Investigation on boundary condition for magnetic vector potential applied in FEM for 3D electromagnetic computation

摘要

Since BC definition of vector potential variable is often confused or even amphibolous in finite element computation, especially in the case when people have to give a boundary condition in commercial EM software implementation, thus in this paper investigations on this problem is presented to show the influence of various boundary conditions for vector potential variable on software simulation and further discussion is also given on the reason of BC problems.
