Hi Peter, well I managed to implement your hint, as well as splitting/uniting the surfaces accodingly. However for the assignment of the materials I only have one "body" available, where I need 3 (the casing made from Al, the wires made from Cu and the "inner part" made from air)...

Hi Peter,

thanks for the info. I don't have a mesh between the outer cylinder and the inner wires. I'll put in something and come back to you.

Cheers,
Robert

Hi Peter, thanks for the hint. Well in my sif file, your second suggestion is implemented by default. Also, regarding your first suggestion, there is already a "solver 2" part in my sif. Would you like me to just replace the default part with yours or additionally place it in my sif. Also,...

Sorry, I forgot a sketch of the layout. See the attachment.

Dear Peter, thanks for your reply. I tried it, and it worked. Basically what I would like is the electrostatic field of: a -30V - potential on the 4 wires and a 0V - potential on the mantle. Since I assume that the electrical field calculation is a very simple task, is there a tutorial how to do it?...

Dear Elmer-community, First of all, the context: I'd like to use Elmer for static electrical field calculations for a particle physics detector. I started with GMSH and created my detector in SINGLE parts (basically a tube with wires in it). The reason why I chose single parts were my geometric cons...
