Elmer Discussion Forum

Hi everyone,

I collected the informations in the forum and tried to make my own simulation for a wound field machine. And the the flux lines for the first time step seem right. But the problem starts at the second time step. I applied the anti radial projector for both the stator and rotor side boundary. Attached is the sif file I used. I used gmsh to generate the mesh file, I use one mesh file so I applied the discontinuous Boundary to make the mesh rotate. From my point of view, it seems the periodic boundary doesn't work after the mesh rotating. But maybe I did other things wrong in the sif file. There are no currents in the stator, in the rotor I applied the DC currents for both windings. Thanks a lot, if someone can give me a hint.

Best Regards

The sif file is here.

Hi

Usually when the symmetry projectors are anti symmetric so should the rotational one be. Maybe try with: -Peter

Hi Peter,

thanks. It worked.
