How can I create a new boundary condition on a comsol? I use a plasma module and I want to apply a new condition to the 3,4,5 panes. There are no boundary conditions on the comsol!
V:potential
n:Normal vector
you can use the additional weak conditions at will to add everything you can express in vali equations
(you might need to turn on the Preferences - show "Advanced Physics interface options"
Please find here a discussion that can help you

Thank you very much for my suggestion, I went to this stage. But in writing I had a problem, how should I define a relationship for a comsol? Please write it and give it to me if you can.
Weak Constraint ---> User defined ---> then, in the "constraint Expression", write your relationship.
