Using Variables for Lumped Port Excitation in HFSS

    • Ata Vafi

      I am using the IronPython command to assign lumped port excitation in Ansys HFSS. During this process, I encountered an issue with setting the starting and ending points using variables in the script. It seems that the command only accepts constants and does not work with variables.
      I want to define the starting point as [$x1, $y1, $z1], and the end point as [$x2, $y2, $z2], by writing these equations in the expression. However, when I attempt this approach, Ansys HFSS reports an error saying, "Length of port lines must be greater than 0." Strangely, when I replace the variables with their numerical values, the command works successfully. Does anyone have experience with this issue or know how to resolve it?

      Your help would be greatly appreciated!

      It is easier to use PyAEDT to accomplish this task.
