Hello, I am fairly new to COMSOL Multiphysics and I am trying to build a capacitor enclosed by a series of circular rings in 3D.
I have attempted it by building a series of helixes with 1 turn along with a radial and axial pitch of zero.
However, this results in an error where the program says that the geotmety has intersected itself.
I have been able to build it in two dimensions as shown in the attachment but I want to try to get it into 3D.
