Symmetry for "Electric Currents (ec)"

Hi All,

I have a symmetric model using "Electric Currents (ec)", so I am wondering if there is a symmetry boundary condition in Electric Currents like other physics? (I tried right-clicked on the physics but the option is not there) Thank you.

For isotopic media (conductance, permittivity) I think zero charge will do the same thing. Is that available?

Hi,

The default "Electric Insulation" boundary condition acts as symmetry boundary condition in Electric Current physics. Similarly, for Electrostatics, Zero Charge boundary condition acts as symmetry BC.
You would however need to be careful to apply the voltage or current input to the symmetry model as you would have to manually consider the symmetry factor here.

Best Regards,

Thank you so much for both of you reply, I can't find zero charge in there as well, soI will try using insulation condition as symmetry plane.
