Near field data as impressed source
Altair EmployeeHi, when I use the AP card to construct a planar aperture and import an .hfe file as an near field source, the input information is always wrong.
Here, I define three points as the S1 S2 S3 vector to indicate the info of aperture. And the Edit Feko commond I write is as follows.
DP P1 0.35 -0.3 0.2
DP P2 0.35 0.3 0.2
DP P3 0.35 -0.3 2.2
AP: 0 : -2 : P1 : P2 : P3 : 1 : 61 : 221 : 1 : 180 : : : : 'PO-NFD.hfe' ** NFD
However, there is always some error:
ERROR 30239 in line 5 of the file PO2step.pre: Undefined angle between three vertex points (same points)
Could anyone provide me some help about this? Thanks.

Altair EmployeeHi, Johan,
Thanks a lot. Your method solve my problems perfectly.
When I built the DP card manually, I just used the format of the example in the FEKO User's manual.
Also, I need to pay attention to those card position.

Dear XuWang
I believe the problem is with the DP cards you defined manually. The spacing between the parameters are incorrect.
I would suggest that you use the 'Point (DP)' option in the Define group on the Home tab in EDITFEKO to define and edit your DP cards. This opens a dialog on the right where you can enter the required parameters and then automatically writes the card and ensures the correct spacing between parameters. The correct format for your first DP card would then be:
DP: P1 : : : : : 0.35 : -0.3 : 0.2
Also note that sources should be defines below the EG card (which signifies the end of the geometry definitions and the start of the solution setup. Sources are usually defined after the frequency definition (FR card).
