Elmer Discussion Forum

Dear Kevinarden,

I double checked the bodies and they are correct. Body 1 is core, body 2 is coil and body 3 is air.
I made some slight changes in sif file, but the problems remain the same. Do you know what is wrong and how to solve it?

Dear Kevinarden, Thanks again for continuing to help me! I feel like I'm progressing in my learning, but there are still doubts that I would like to resolve. When I simulated the SIF file you sent me, magnetic flux density, magnetic flux strength values appeared! Which is already an evolution! Howev...

Hello Kevinarden, Thanks for sending the links. I analyzed the test case you sent me and realized that it is a 2D example with analysis of some current variables. I apologize, as I forgot to inform you that I am trying to simulate a 3D reactor. I want to apply 30000A to the coil and would like to ha...

Hello kevinarden, Sorry for the delay in responding here again, but I was working on my simulation, following your suggestions. By the way, thanks for the tips! I'm now unsure how to apply the current value I need to the coil. After reading several posts on this forum, I used body force and componen...

Sorry, I forgot to attach the FEMM and UNV files.

Hi kevinarden, Thank you very much for the link! I'm using it to study, however now I am facing another problem. I'm using FEMM software to compare results with Elmer, in order to better understand the software. I applied 30000A to the FEMM and obtained a current density equal to 150*10^6A/m2 and a ...

Hi kevinarden, Thank you very much for your tip! It worked! The previously error disappeared. Another convergence error appeared, but I managed to get it right. I have attached the corrected SIF file for the record. I'm new to Elmer and my goal is to simulate a transformer and then apply current tra...

Hello Felix, I've tried many times to use Freecad to design this reactor and mesh it, using different approaches (Boolean Fragments, Compound, etc), and it didn't work. I had the same error on Elmer: ERROR:: DefineCoilCenter: Coil has no volume! I agree with you that my mesh seem inconsistent. As su...

Hello thalesmaoa,

Thank you for you reply!
Please find attached the Freecad file.

Hello Felix,

Thank you for the prompt answer! I'll try to follow your advice!

Best Regards,
