  My model contains a large table model and a PCB model. There is an error in the meshing of the microstrip line ports on the PCB. The specific issues are as follows"Port refinement, process hf3d error: Mesh segments could not be obtained for an edge of terminal Rectangle3_1_T1 assigned to port MDI_N_PCB.. Please contact Ansys technical support."

  Hi,
  Thank you for reaching out to the Ansys learning forum. Your patience is much appreciated.
  Are you using Ansys HFSS design for this simulation? If so, please share details like how the PCB model is imported? Some times, re assigning ports again in HFSS design solves the issue. You can also do model preparation to check if the model do not contain any mesh related errors.
  Best regards,
