Hello,
I would like to apply an interior boundary condition in the general PDE module in order to have a discontinuity in the dependent variables across the internal boundary. Ideally, I would apply an up() and down() constraint on the boundary for the discontinuity. It seems like Comsol defines additional shape functions described as "slit" in other modules, but I don't understand how to add these in the PDE module. Is it possible to do so in PDE modules?
Thank you
Alex
