How to use the user law of electric potential boundary

[husanhao]

Dear all,

I would like to set the user law of the electric potential for the inlet of the electric arc model in CS 3.0.0. However, the GUI doesn't allow me to set the user law for the electic potential. (Please refer to the attachment file). I would like to know is there any way can set the user law by using GUI, or I need to use the subroutine to do that, thanks.

Best Regards
Eric

Hello,

You can impose user low for electric potential with cs_user_boundary_conditions subroutine.
I do not know why the functionality is deactivated in the GUI. I will check.
