To fully exploit all symmetries and save computational cost, a 2D-axi model is used geometry. However my target resonator mode is symmetric up to a phase modulation in the fields.
With the Electromagnetic Waves, Frequency Domain (ewfd) physics, I can specify this phase-symmetry by the azimuthal mode number (m), which gives me the desired resonator modes (for m=1).
So far so good.
From the resonator mode I also know the wave vector (along the axial axis), so to reduce the mesh density I would like to use the Beam Envelope (ewbe) physics.
However ewbe does not account for the axial phase-symmetry, i.e. it won't let me specify an m (implying it only solves for m=0).
Is there a way to change the PDE of ewbe to account for an m != 0, like ewfd does ?
