Re: What's the best hardware - more cores on CPU or more CPUs?

Hi, openEMS does not use the GPU and it does not scale very well with the amount of CPU cores. Usually you get the best speed using only 2 or 4 threads. The CPU cache size and CPU to main memory bandwidth/speed is much more important I think. I hope this helps. br Thorsten Thank you. It does help. ...

Model a coaxial probe. Support for lossy dielectrics?

I've never used openEMS, but are thinking of using this to model a coaxial probe. This is basically a piece of coax that's cut off square at the end, and a groundplane attached. The probe is then pushed up against a material under test (MUT), such as a solid or immersed in a liquid. The amplitude an...
