FEKO: error 52001

GabriB

Hello,

I had the following error in simulating in FEKO a scenario with an impressed nearfield source.

The normal vectors on a CFIE/MFIE/thick coating body point outwards. All sources should consistently be defined outside of this body.
What does it mean? How can I fix it?

Hi GabriB,

One requirement for using CFIE/MFIE/thick coating is that the back side of the faces be field-free (for a close metal structure with source somewhere outside the normals would then have to point outwards). Please check the normal direction of your faces and flip them if necessary.
If you'd like, I can take a look at your model.

Best regards,
Torben

How can I flip the normal direction?

Torben Voigt

Right-click on face → Reverse Normals

It is possible to see the normal direction

You've probably figured it out on your own by now, but still:
