Hey everyone,
I am trying to test the flux leakage from a solenoid (in DC) given a variety of core shapes. I am new to Comsol and, after a bit of playing, decided to simplify the problem to the field generated by a cylinder, and then to build the solenoid back up to make the analysis more thorough.
I am using the AC/DC module, and I have a cylinder with potentials at both ends. When running Comsol, the potential shows up on the cylinder, but I get no flux lines.
I've tried grounding one end, adding surface currents ( under boundary settings and subdomain settings and edge settings).
I feel I am missing something elementary here; as I mentioned, I am new to Comsol so any help would be appreciated!
Further (and finally), is there any way to create a helix or solenoid in 3.5? I found tutorials for 4.2 but the interface is completely different so I have no idea how to start it.
Thanks in advance!
Jonathan
