Is there guidance on when and how one can combine simulations with varying excitations?
Hello, I am currently planing a big simulation that needs to be repeated several times with different excitation sources(voltage sources for farfield calculations, mostly). Is there documentation on what setups and settings to use to minimize total simulation time? I assume that if I setup the problem as different…

How can I do Characteristic mode analaysis correctly in this antenna?[ FEKO-2023.1]
Hi, I am trying to perform a characteristic mode analysis for this conformal antenna, but every time I finish the simulation in postfeko, I see a warning that "This mode was not calculated over the entire range, more modes should be requested." This issue occurs every time I request more modes. How can I get the result…

Import CSV in FEKO to generate a frequency signal
Hello everyone, I am currently trying to simulate an ADS-B transmitter antenna in FEKO. The antenna design is done, and I want to change the source voltage to a desired signal (PPM signal), which has been logged in a CSV file. Is there a way to import the CSV file into FEKO and generate the signal? Thanks for the help.…

Can anybody please fix the 3D pattern in postfeko of this simple patch antenna?[ FEKO V. 2023.1]
Hi, From this attached simple probe-fed patch antenna, I am getting the 3D farfield in postfeko much much below the antenna structure, so I am getting negative value for the gain and directivity. I think there are some issues with the antenna layers/faces; therefore, the radiation field is always below the antenna. Can…

Antenna Array Issues
Hello, I am trying to verify different sizes (infinity x infinity, 16 x infinity, 16 x 16) of the referenced Dual-Polarized Planar Ultrawideband Modular Antenna Array [1]. I have created a simplified parametric model of the Unit Cell (attached herewith) in FEKO. Instead of modeling the connectors and energizing using…

Tutorial Thermal+Structural analysis in SimLab after Feko simulation
Electromagnetic losses, computed by Feko, become volume heat loads and surface heat fluxes in SimLab. There, OptiStruct is used for the subsequent thermal simulation followed by thermal stress and deformation. This tutorial explains the detailed steps in SimLab. It is intended for Feko users who are not familiar yet with…

How do I optimize a model that is split in frequencies?
I am currently trying to optimize a broadbanded device that requires the use of different solvers and meshes for different parts of the spectrum. So, several meshes and some frequencies computed with MoM, some with MLFMM and some with MLFMM/GO. Computing the low frequencies with MLFMM activated causes crashes/convergence…

How to calculate SAR for an implanted antenna in a medium
I'm a beginner with FEKO, and I'm trying to figure out how to calculate SAR for an implanted antenna in a human medium. I've placed a dipole antenna inside a cylindrical body like this. From my simulation results, the near-field SAR distribution and the peak spatial-average SAR are different by several orders of magnitude.…

Fix ERROR 40619 Intersecting elements found in EDITFEKO
Description: [I need to automate an antenna array generation. First, I import a .cfm (mesh model) file of my antenna. Then, I generate a finite ground plane. I end up with 13 intersecting triangles. While I can manually delete them and create new ones on CAD FEKO, it is not a solution to my problem because this has to be…

ERROR 50163: Internal Feko error.
When I was using the GPU acceleration feature of RL-GO, I encountered ERROR 50163: Internal Feko error. My model has been meshed using flat triangles, and the rays of RL-GO have been set to the "Fixed grid increments" mode. As far as I know, these two settings meet the requirements for GPU acceleration of RL-GO. However,…
