Hello Ivar,
I need a big favor from you.
Its a request since my model is giving weird results. I have worked on it but I need to get the physics right.
So I decided to try the time dependent study which should give the instantaneous current values which are then used in the stationary study, that is my thinking.
So I created current variables in the parameters section, ix and iy. These currents are dependent on time, t. So I thought the parameters will be able to access the variable t, but ????
I defined the current in a coil as -ix on one coil-side and +ix on the other coil-side, is this right in the multi-turn coil domain under MF.
The other difficulty I faced is defining relative permeability which will change depending on the H and B values for non-linear material, since mu_r = 1/mu_0 * B/H, where B and H are from the BH curve.
So how do you go about this issue. I was not able to define relative permeability as defined above.
I also Imported with both the 1st and 3rd quadrant, you can check a plot to see how it looks like and I hope its OK.
From the plots of the magnetic vector component, it can be seen that the flux is not penetrating the silicon steel sections ????
Regards and thanks in advance
NB: I attached an m-file by mistake but the model is as attached.
I also submitted the same to the technical support.
