Oersted field in a nanoconstriction

Please login with a confirmed email address before reporting spam

Hello,

I am trying to calculate the current induced Oersted field in a nanoconstriction structure. I have implemented the current density applied to the far face of my bottom layer using the magnetic fields interface however I cannot achieve any sort of results for my model. Without implementing the background field by solving for a reduced field or setting any initial values the solver simply produces null equations for the magnetic vector potential. However once the background field is implemented the solver now fails with the following error:

Failed to find a solution. Auxiliary-space Maxwell Solver is only applicable for edge finite elements. Returned solution is not converged. Not all parameter steps returned.

Please find attached my current model, any help would be much appreciated as I am at a loss of where to go from here.
