Circuit+AVHarmonic with open and closed coils

Post by fjimenez »

Hi Everybody,

I have been experimenting with circuits and the AV Harmonic solver and I am wondering if the following set op can be solved for using elmer.

What I have tried and does not work:
  • Use coil solver for the coil and wire. Coil Solver tries to solve for all components in the .definition file. It does not work because first, if I use coil closed = True it assumes all components to be closed and this is not true and second if I remove this flag it does not work beacuse it has no way to solve the closed coil.
  • Use coil solver for the coil and W solver for wire. It does not work because the coil solver is still trying to solve for the wire even if I don't attach the solver to the wire body
Questions:
  • Is it possible to avoid the CoilSolver to solver for a component?
  • Can I declare the W vector in the body force section for the coil? I guess I cannot use current density like in other examples because the current
    density is calculated in the circuits solver.
NOTE: this same setup works if I use two closed coils.

Here is a test case with a very coarse mesh.
