Re: PMSM Simulation with Symmetry BC

Yes, I have checked the boundaries using ElmerGUI. Boundary 6 is a so-called master of the rotor and boundary 7 is the slave boundary where the values are projected. I have the same pair of boundaries on the stator side as well. I used the induction machine example form Pavel as a reference.

Re: PMSM Simulation Symmetric vs Full Model

I could not attach more than 3 files for some reason. Here the symm model files as well.

PMSM Simulation Symmetric vs Full Model

Hello, I have made 2 models, the first one is called "model_full" and the other one "model_symm". The first one is based on the full PMSM model and the second one has only 1/3 of the model and uses the symmetry of the machine. It seems that the models give identical results (see ...

Re: PMSM Simulation from Pavel in ElmerFEM 9.0

That is what I did in the example posted on this forum, see "PMSM Simulation with Symmetry BC". But it seems that the model is not working properly. It would be great if someone could check what I did wrong in the SIF file.

Re: PMSM Simulation from Pavel in ElmerFEM 9.0

Hallo Peter,

thanks for the explanation. I think as well that it is better to use the two independent meshes. I have tried to do that with the symmetry boundary conditions. But it is not working as expected. I opened the case at this forum entitled "PMSM Simulation with Symmetry BC".

Re: PMSM Simulation from Pavel in ElmerFEM 9.0

I made some tests and it looks like "Mortar BC = 3" cannot be deleted from the SIF. However, the number 3 is not relevant. It can be any number other than the numbers used in the defined boundaries. If deleted the solver shows "discont" message and appends "discont_" to...

Where i can find the "savescalars_mask" test case?

Re: Understanding SaveScalar Solver

Hello Peter,

so, for the MagnetoDynamics solver when defining two radii inside the body section the torque is always calculated? The radii can be named randomly like "r1" and "r2" or the naming should be used as in the example of Pavel "r outer" and "r inner"?

Understanding SaveScalar Solver

Hello, i am trying to understand how the "r outer" and "r inner" radii are connected with the SaveScalars solver (Solver 5 in the code) used in the PMSM machine of tutorial from Pavel. Also how does the solver knows it should calculate the Torque? Body 16 Target Bodies(1) = 16 Na...
