Hi
first of all, isnt it easier to model that as a 2D cut view (independent of Z) with out of plane flow (Z) of the current, in 2D

Good luck

Hi Ivar, thank you for your reply.
I'll try the 2D cut as you said! I have no problem with the 3D run time sim.
When i use the non linear relation for μr in 3D i receive a n error window....and when i use the BH-HB curve i've got the same result just as the model with μr=const=7000 .
I didn't understand extactly the second part of your saying about the without current flow on z? You mean that when i use the 2D cut this is an option of the geometry?
Thanks again!!

Hi
Indeed, in 2D you can have current flow along Z the perpendicular direction, or in plane along a combination of X.Y
It's just easier/quicker to debug in 2D, then run a 3D model. For the BH have you checked the Model Library files with saturation iron cases, that gives you the indications how correctly map in the non-linear B-H mode

Hi Ivar ,
I didn't see all the models at the library but I'll ckeck it out...and I'll inform you about my progress.
Thanks, for your time!

Hello Ivar,
I don't want to bother you but I need your lights.
As far as I understand materials/ACDC modules is your specialty.
I want to upload a model but it is about fluids flow.
I dont know how to do it due to its size(60ΜΒ)...Any ideas??
If you have time and i achieve to upload it, could you check it?You or someone else on this field.
Model :
I want to load a chamber with Argon but inside it i have already air. And I want to see in which way the argon is moving inside the chamber and its concentration. This is a time dependent model, so my last question : Comsol multiphysics counts real time in sec or this is about the time dependent differential equations?
Thanks in advance

Hi
its far easier to upload models once they are reset :
Edit - clear all solution, clear all mesh, File - reset history then save as with a new name and upload ;)

Good luck
