I see the following warning:
Warning 2757:A triangle is too thick as compared to the lateral dimensions (SK card).
What does it mean and what should I do to fix it?
This warning occurs when, for example, using the skin effect (lossy metallic surface) or thin dielectric sheet. For accuracy reasons it is necessary that the lateral dimension (square root of the area of a triangle) be larger than its thickness. The thickness is that specified when using a lossy metallic surface (skin effect) or thin dielectric sheet. Users familiar with EDITFEKO will recognize these options as those of the SK card.
FEKO will give this warning when the lateral dimension is equal to or smaller than the triangle thickness. It is recommended for accuracy to keep the lateral dimension several times larger than the thickness.
The lateral dimension is controlled directly by the triangle mesh size (which is based on the frequency). Therefore it implies that an upper frequency limit exists for which FEKO can accurately model the skin effect. This upper limit is of course strongly dependent on the thickness and conductivity of the lossy metal.
Hello !
I am having the same problem but don't quite understand what would happen if the triangles get small in comparison to the thickness.
Thanks,
Pierre
