Re: Use of multithreading

Hi,

fastest and multithreaded is the same and thus you can omit to set this at all.
As far as number of threads is concerned, that depends on the simulation.
Start with e.g. 2 and work you way up to the number of cores available to see what gives you the best speed.

best regards

Re: Bug fix for Qt problem

I have pushed a slightly modified version to github (check for Octave + Windows), will be included in the next release.
Maybe you can check the modified version?

Re: How to make a lumped inductor?

I don't think that SMD inductors (with any reasonable value) do exist. Please correct me if I'm wrong. Theoretically something like this would be possible in a numerical tool but I would not see the point if it does not exist in the real world. As far as a matching network goes I recommend to use a ...

Re: A Luneburg Lens fed by an aperture patch antenna

I think these functions just plot what you feed in. Have a look at some of the antenna tutorials for more details and examples.

Re: Mesh alignment

Hi, I'm not really sure what you mean or what exactly the problem is, but the meshing will always have influence on the results and accuracy. Thus make sure to keep it constant during your investigations and refine it until the results converge. Otherwise I don't really know how to answer your quest...

Re: Bent Patch Antenna

Hi,

the example/tutorial shows the cylindrical mesh and how it can easily simulate a bent patch. But this means it does only work for everything that can be expressed in cylindrical coordinates.
That means no, a cone is not that simple...

Re: Strange behavior from rectangular waveguide

I assume you have PML at the start and end? Can you try to make it PEC inside the PML and only finite kappa inside the "normal" domain? Maybe the PML does not behave well with high conductivity. As for -50dB vs -100dB: the mode matching is based on the analytical modes and therefore never matches 10...

Re: Python installation : fatal error: CSXCAD/ParameterObjects.h

Well the command looks fine to me. I assume the file "/opt/include/CSXCAD/ParameterObjects.h" is indeed available?
