Neumann BC with Static Current Solver
Posted: 21 Nov 2023, 06:15
Hi,
I'm currently trying to model the stator of a motor but I have some trouble to apply the current density in the conducting part.
To simplify the situation as much as possible, I only consider one phase in static configuration. Everything is linear.
I'm using the StatCurrentSolver to simulate the current injection in the conductor based on the different models I could find related to this topic on the Forum.
When using Dirichlet BC (imposing the potential difference through the conducting domain), everything seems to work (At least I get a decent solution). However, I would like to obtain a somehow uniform current density by imposing the value of J instead of the potential (Neumann BC). But, in this case, I can't get any convergence.
As I'm very new on Elmer, I'm probably missing something quite basic.
(Here is the link to the mesh file in case you need it as the file is too big. Sorry for that...)

Thanks a lot,
