Hi I want to find the magnetic field result from DC current flow through the rectangular transmission line numerically by using the finite difference. the solved equation is curl curl A =µ J , with div A=0, and J is a uniform current on the crosssection. I implement the MATLAB code , but...

please , can you show me some examples to discrization of the magentic field potential in x-y-z plan , if anyone has a paper of chapter of book can help me. and which methods could be stable numerically

do you mean that ∇^2 Ax=Jx, ∇^2 Ay=Jy, ∇^2 Az=Jz, and Ax, Ay, Az lies on the grid nodes

because the A is a vector then must be put in links of the grid, not on the nodes, or?

thanks, but i have another question , the reusltant equation will be ∇^2 A=-µ J, and A is a vector, not a scalar, this one is not Laplace , is Poisson, or

hi everybody i want to solve the wave equation of the magnetic vector potential numerically in x-y plane grid, curl curl A= µ J anyone can help me thanks in advance
