Periodicities in 3D transient magnetics
Altair EmployeeHello,
I would like to use periodicities for a toroidal core in Flux3D transient magnetics (12.3). I have set up a simple example with a non-linear steel core and a non-meshed coil. The periodicity is set to cyclic conditions but somehow the magnetic flux won’t concentrate in the steel region.
I tried the full model with the same geometry and it looks fine, the flux is concentrated inside the steel region. So there must be a problem with the boundary or the periodicity.
How do I have to set up the boundaries/periodicities/formulations to get to correct results?
Thanks in advance.
Best regards
Patrick

Altair EmployeeHello,
Here is a link that gives you details on the use of periodicity in Flux:

Altair EmployeeThanks for your replies.
Symmetries are working for me as well. For the periodicity I tried to edit the non-meshed coil and to change the boundary conditions like you suggested, but I still get the same results.
I set up the model with meshed coils but no difference there.
I have read the documentation on how to use periodicities and think that I have taken into account all of the mentioned points.
Or am I missing something in my model? Or is it not possible to model such type of periodicities?
Best regards

Hello,
I never used periodicities, but I used symmetries. Your problem may be the formulations for the non-meshed coils:
Did you tried to change in 'Edit Coil' --> 'Electrical' --> 'Symmeries and periodicities: ...' between 'in series' or 'parallel'?
An other possibility to change the boundary conditions are face regions. You can try to set them on the faces between the periodicities.
I hope this would help you a little bit.
