    HFSS integration line problem

    Hello all,
    i recently started with hfss and needed to add a wave port however while defining the integration line for the wave port to the face parallel to yz plane , the distance along x-axis is showing zero , this causes the wave to oscillate about a point rather than travel along a line





    Thanks Again

    What do you mean "oscillate about a point"? What are the boundary conditions on the four port walls?

    Re: HFSS integration line problem

    It seems you want to feed a simple wave-guide. If so, why do you define an integration line? HFSS considers wave-port as an infinite wave-guide which automatically feed correctly, I mean with correct polarization and the dominant mode. In lump port definition you have to define an integration line.

    Re: HFSS integration line problem

    I see in your message log that you performed a geometry modification on your boundary. If this modification touches the integration line it is removed and needs to be reassigned after the modification. I'm not sure if this will solve your problem but at least it will solve the message in the log.
