There is a lightbulb icon next to each primative. You should be able to hide the bounding box.
That said, on all the windows machines I use this is hidden by default.

Re: Getting openEMS to execute more quickly
I run it on a 10core(20thread) i9 machine (gen 9). OpenEMS isn't great at utilising all the cores and I get faster results limiting it to about 8 threads. I believe it's a memory bandwidth problem. Hence my best guess for an ideal machine. 1. Lots of cache memory 2. Fastest memory you can get(with m...

Re: Electrically Small Antenna - S11 > 0
I think this is just quantisation noise. The values are so small the limited precision of the digital math may be having an effect.

Re: Electrically Small Antenna - S11 > 0
While I haven't looked in detail at this. For the small size of the antenna and the huge frequency range you are trying to simulate, I am not surprised that it it taking many hours, perhaps hundreds of hours to simulate. Hopefully you are already aware of the limitations of electrically small antenn...

Re: Use of multithreading
As Thorsten says, there is an optimum number of threads. I run this on a 10core i9 processor. But in general, it normally runs faster if I limit the threads to about 4. Other speed sup tricks include... Lowering the stopping criteria. You have it set to -40db. You might be able to get away with anyt...

Re: How to add my own model to openems
The software can import STL files. Most 3D software can export to that format.
The source code is on the openEMS GitHub.

Re: Interfaces to openEMS
I would say a big advantage to Octave is being able the availability of example code and ease of plotting results. Matlibplot under python is very similar to Octave plotting, so that would help if you go Python.

Re: GPS antenna with zero and 90 degree feed ports
I think I have it working. The answer was buried in the forum, but needed an extra bit of digging to work out how to add a delay to a lumped port. The simplest way is to add a Delay as shown below start = [feed.pos 0 0]; stop = [feed.pos 0 substrate.thickness]; [CSX port] = AddLumpedPort(CSX, 5 ,1 ,...

GPS antenna with zero and 90 degree feed ports
Hi all, I need to do some work modelling a GPS antenna(RHCP patch). Physically, this will be fed by a 90 degree hybrid to achieve the desired circular polarization. To simplify and speed up the simulation, I don't want to try and model and simulate the hybrid. I would like to excite my antenna via 2...

Re: FDTD Matrix
You will need to use paraView to visualise. Also, as the material is a volumetric solid, you will probably need to do some section cuts of the data to see inside.
