I am new to COMSOL and I have been using it for a few days. I created a model for an optical waveguide (Cylinder). after computation, the electric field was not propagating (z axis was the propagation direction). When I modified the geometry and made the x axis to be the propagation direction, the problem is solved. Why is that? You can also see the attached snapshots.
