Dear all

I am trying to create a model with a very thin wire. The wire is supposed to be have a circular cross-section of 1 cm dia and be about 1000 m in length .
I need to excited wire with a (sinusoidal) current in the small segment and simulate the current along wire then calculate electromagnetic field around wire. I started with a RF in 3D, but I have problem in meshing and running the model.How I can mesh and run this model?

regards.

Hi

if you do not need to resolve the wire (internal info inside the wire) then use an edge current, its easier ;)

Good luck
