Stranded conductor - simple 3D current in coil implementation
Hello,
I am trying to build a 3D coil in an electric machine and to add some current in it.
Known approach: Follow the 3D inductor.pro example, and parametrise the current for each mesh element within the 3D coil. However this is hardly scalable for more complex / various coil geometries.
My approach: I add a plane coil_cut within the 3D coil and add some current density vectors normal to this plane. Considering that the coil is simulated as a 'conducting element', the current should be flowing throught the whole coil.
Question: How to define a stranded coil? Meaning: How to set the coil to be conducting the current imposed but to not be affected by the possible eddy currents generated by the magnetic field in the coils? (The coil might be made out of thin copper wires, where eddy currents are negligeable)
Possible solution: Should this happen in the "formulation" part of the script? Defining a formulation for the coil and another formulation for the rest of the machine?
