RE Symmetry in the EM wave model

Please login with a confirmed email address before reporting spam

Hi,
I have been looking through the problem of applying symmetry to the waveguide. (across the height of the waveguide, z-axis) to reduce the computation time . I came across PEC and PMC BCs. I try to apply PMC boundary condition on the top of the waveguide (i draw it one half of its original height) . But i cannot get the electric fields to simulate at resonant frequencies( i can see the field strength in the legend though at certain frequencies but cannot plot the Electric fields, they appear not to be travelling visually through the waveguide)). Also, if i do apply symmetry, do i need to half the power input to get the same results (Electric field strength). Would appreciate your response.
