[Getdp] Convergence of magnetodynamics

Recently I faced with necessity of iterative solver use for
magnetodynamics. I started with this case:
I used getdp with petsc, and I could not get to convergence.
I have tried:
getdp indheat.pro -msh indheat.msh -solve MagDynAVComplex -solver solver.par
I have tried also other combinations of preconditioner and solver (icc +
cg, ilu + gmres, bjacobi + gmres, bjacobi + cg ...).
So far the best convergence was with icc+gmres, which was only to 1e-9
after 1000 iterations, but the results were unphysical. Direct solver gives
Do you have any clue why is there such behavior and is there a way to get
iterative solver work?
Best Regards, Vadims
