Hi, everyone,
I'm new to COMSOL, so I'm still getting used to things, but I was wondering if someone could help me with identifying boundary edges.
I've attached the geometry I'm working with right now. I've identified three pairs of edges in the definitions section (the geometry is supposed to be the surface of a tetrahedron, so that way if you fold the domain and glue together the identified pairs of edges, you get a tetrahedron).
I'm not sure how to get this reflected in what I have so far. To make the identifications properly, I need to make a condition that any solutions of the PDE that are calculated are even along the boundary lines (e.g. if we're considering the bottom edge, I want u(x) = u(-x), with the midpoint as the origin). I've tried playing with boundary conditions and the geometry, as you can see, but to no success.
Thanks in advance for any help.
(Note: I know that the 3D geometry allows for an actual tetrahedron. I'm interested in the unfolded planar geometries only, so using that won't help).
