Creating insulated electrodes attached to scalp / brain

Please login with a confirmed email address before reporting spam

Hi there, I am completely new to Comsol. I am attempting to model the field density and distribution within brain tissue by means of insulated electrodes on the scalp, similar to the concept of transcranial stimulation. Although I would like to use complex multilayer models in the future, right now I am trying to just figure out how to set up insulated electrodes on the surface of a sphere with voltage of 2V and 1-3 Amp currents. I am also wondering, if there is a way to set up alternating current system between two electrodes. Thank you so much.
