In HFSS you can do very easly.

Draw your structure as line object, then sweep it along the axix by 360 degree

Its not difficult at all. Simply make a horn with som thickness of the walls. Then embbed copper bars of certain thickness and depth in the outer walls.Finally substract these bars from walls which will create corrugations
