FEKO - Singular field on one of the triangles.

So I imported a drawing into FEKO (from HFSS) because I did not want to draw it again. I did the meshing, removed intersecting triangles and all that.
When I run a simulation, i get this error:
"Singular field found on one of the triangles". And it aborts. Anybody knows how handle this error?

Thanks,

If the error occurs during field calculation stage, it is because you are requesting field points on a triangle. Field points can not be computed direclty on a triangle. If the error occurs during the triangle integral setup stage, it may still be a problem with your mesh. You can check the error message in the OUT file for the triangle number. Then in POSTFEKO find that triangle using the black binoculars button on the left. Once you have that triangle, you can go back to CADFEKO to correct it. I remember seeing a video on their site how to fix minor meshing problems.
