How do I incorporate pin diodes for discretising a transmission line

  I need assistance with putting pin diodes where these vias are for this strip line transmission line. Can anyone assist? I have a data sheet for the pin diodes where these. How do I use the rlc circuit feature to create the diode?
  thanks

  Hi Sabir,
  You can perform HFSS + Circuit co-simulation as shown in the attached link PIN Diode simulation in Ansys HFSS + Circuit co-simulation | Part 1
  Thanks,

    I have tried doing that. I feel like he is missing several steps. How is he modeling the diode itself? Is he using a box and sheets? He does not explain that.

  hello, I need assistance with my model. I am having issues with Parasolid related errors. I do not have any intersecting objects. Can you provide me insight why this is happening and how to resolve it? Also how do I properly substract the blue tiny boxes (pin diodes named pd- which I still need to figure out how to turn them into). For whatever reason when I try to substract them out from the substrate, the substrate disappears. Are you able to look at my aedt file and assist? I will attach it later today.
