Hi all, I am getting an error which says it is an internal error. I always gets stuck at 7%. It happens with all kind of mesh sizes (Fine, Standard and Coarse). I am attaching the model here. circular_2wg.cfx
Hello everyone, I have a mode of a propeller in which I have only faces and edges. However, it is a 3D figure. When I want to make the medium of the model a dielectric medium, I get to choose between PEC, layered dielectric and default. The thing I do not understand is how can be a layered dielectric be a medium? Is it over a medium already? What exactly does it do when I select the medium as layered dielectric?
I want to simulate an array of Vivaldi antennas, which is obviously very resource intensive. I have read that one can use DGFM to solve antenna arrays and that it will help to run the simulation faster, and with less memory requirements. However, I have also read that you cannot use DGFM with regions that use SEP for certain versions of FEKO and this error message is displayed to me when I run CEM validate in CADFEKO. I have updated my FEKO version - it is FEKO version 2018.2.1-343574 . Is this one of the versions that cannot use SEP and DGFM at the same time? If I cannot use DGFM to solve the array what other methods can I use to help lessen the amount of memory and time resources that is required to simulate the array? Is there a way to fix this? How does this FEKO version relate to FEKO 14 (since I read somewhere that in FEKO 14 this problem was fixed)?
Hello everyone, I have a small doubt regarding the mesh size of the FEM solver when the material inside a 3D body (for RCS consideration) is characterized with some finite conductivity. I can see the standard mesh default for FEM is around `\lambda/10` but with a conductivity of 10 inside a material (`\epislon_r = 1`), the mesh size for standard meshing is around `\lambda/145`. Does it change when the skin depth changes? I have attached my cfx here. Cyliner_FEM_V2.cfx
