Hello.
I am aware of the usage of the minimum coupling operators. But I have found a situation I can't get out of.
Let's assume we have a rectangular domain (x€[-1;1] and y€[0;1]) in which a variable u(x,y) is calculated.
For any x, u(0) = +K and u(1) = -K. Therefore, for any x, there is a coordinate y at which u(x,y)=0.
I want to find a way within COMSOL to know or plot the function Y(x) so that u(x,Y(x))=0.
I can't seem to find a solution using minop(u,y).
Thank you for your help.
