Reflection in a boundary

Please login with a confirmed email address before reporting spam

Hi all, I'm fairly new to COMSOL. I have a scalar quantity A(x,y) distributed on one side of a boundary. I want to reflect that distribution on the other side of the boundary - if it's a straight boundary (say) at x = 0, and I know A(x,y) for all x >=0, I want to let A(-x,y) = A(x,y). (I have slightly more complex cases in mind, but I'm happy to start with this simple case!) Many thanks.
