CoilSolver and Massive coils

Hello all,

I've been having trouble using massive coils and CoilSolver.

Please find the simulation files attached here. For the mesh, there is a Salome File to create the mesh.
For the CoilSolver I have simulated using Stranded coil, which works fine. And then I've tryied using a single turn Stranded coil with 'Normalize Coil Current = Logical False'. The current density goes to the roof.
Then, changing to Massive coil, the result is:

Code: Select all

SolveLinearSystem: Assuming complex valued linear system
ERROR:: IterSolve: Numerical Error: System diverged over maximum tolerance.
Note: The following floating-point exceptions are signalling: IEEE_INVALID_FLAG IEEE_DIVIDE_BY_ZERO
STOP 1

With the circuit defined as voltage source, result is trivially zero.

However, using Wsolve results are perfect, agreeing with axissymmetric FEMM results.
