How can I fix this triangular mesh error 2331? Feko V 2025.1

Hello, no matter what surface or geometric body I place in CADfeko via a patch array, there's always a 832, and if I try to fix it, I get a 2331, and that can't be resolved. Only the output file shows the triangles, but in CADfeko I have no chance of getting rid of them—no help entry or AI query has worked so far. The example with the dielectric cube and the dipole works. When I try to replicate it with my setup, one of those errors always appears. Pls try my file and then you find the reason that I am doing wrong pls comment. I am out of any glue so far. Thx

Hello @JensV1DC,

Since Domain Green Function (Finite Antenna Arrays) doesn't allow any overlapping/contacting between elements (arrays), your reflector size for one element should be smaller than the offset dimension (X, Y). So, it is impossible to draw a desirable reflector whose 4 elements are perfectly connected (without any hole.)

I think only possible way is to use a PEC definition from the planar multilayer substrate, which is infinite.

If you want to use a finite reflector, you might use the macro, Generate Antenna Array.

Best regards,

Jaehoon
