a waveguide is a high pas filter. So, if you look to check for its cutoff frequency, you do the simulation on a larger frequency bandwidth and when looking at scattering parameters, you will see when it cuttoff

yes but i would look for data how i find data of waveguide cutoff
Look for the scattering parameters S21 and S11. Since it is a high-pass filter, after the cutoff frequency your S21 should be close to 0dB and S11 should be around -30 dB.
