Hi, I'm working on simulating the HE11 mode in a circular waveguide. From what I can tell, HFSS sorts from the lowest resonant frequency up as it orders modes, and the modes you get will be in some way dependent on the shape, dimensions, and material of the wave port surface. But it seems like there is not a reliable way to predict modes and their order for a circular waveguide. Is this so?
