No convergence in iterative frequency domain perturbation study

Hi,

I want to simulate the magnetic field inside a copper pipe surrounded by a helmholtz pair. No matter which solver I use for the iterative frequency domain pertubation solver, it doesn't converge. Here are some results from all the solvers I tried.

1 2 3 4 5

It always hovers around an error of 500. I use a fine mesh. Some odd things I saw during simulation were that in the study section I get an orange triangle when I select the physics interface and during the stationary study I get inverted mesh elements.
