The pads are rotated after importing to Ansys Q3D from altium

[R_ZH]

Hello everyone,

I'm currently working on a PCB design in altium. After finishing it as in picture 1, I want to import the PCB model to Ansys Q3D to extract the parasitic parameters. I used Ansys EDB to export the PCB from altium, then opened Ansys Electronics Desktop and added Ansys HFSS 3D layout, and import the EDB file. Next added solution step as auto, right clicked the solution setup and export to Ansys Q3D. The model in Ansys is shown in picture 2. As you see, the pads in S1, KS1, C1 and J1 rotated by some angles comparing to altium. I don't know why it happened but I have correct them. Does anybody know the reason and how to fix the problem. Any help would be appreciated.

Best regards and thanks in advance!
