Hi,

I would like to simulate a magnetic field through copper tape wound into archimedian spline.

There are 3 bodies in the project:
1. archimedian spline - copper. Here I inject a current and defined on other end 0 voltage face. 
2. air between the spline winding - air
3. enclosure - air

I did somme basic mesh, which is not very detailed but for now it looks enough. After I try to solve the project it stops after some seconds and return an unknow error. Can anyone check what Iam doing wrong? Thanks.

Here is the project: https://drive.google.com/file/d/1D9v5cP9E9U63L3xNVC9kOCT2oYWjgkYs/view?usp=drive_link

Slowly, I figure out the problem, I dont have a connections in the model, this is an imported .STP file. But looks like I am not able to add connections between faces because because that button is grayed out. Does anyone knows why? Thanks.

Hi

• The geometry must consist of a single solid multibody part.

• A magnetic field simulation requires that air surrounding the physical geometry be modeled as part of the overall geometry. The air domain can be easily modeled in DesignModeler using the Enclosure feature. Ensure that the resulting model is a single multibody part which includes the physical geometry and the air.

To use shared topology see:

, and for single multi body part see:
