AFAIK 1/3 rule has meaning generally in PCB simulations. Probably, ONLY in pcb simulations. So first, there should be an agreement about layers for a tool to work. There is such tool: http://openems.de/forum/viewtopic.php?f=3&t=567 (I didn't try it myself, because it still needs some compiling and i...

t> but your post sounds very negative to me and I do not really like that. Please give constructive feedback I am commenting the discussion about "HFSS or Empire" you have started yourself t> If you have these kind of resources (money) it would make sense to think about a commercial FDTD solver (e.g...

Garias, let me express my scepticism about the configuration. It is exactly the configuration I always try to avoid. There are too many SLOW cores, and too little RAM, and channels per-core. This machine is good for fast repetitive solving of short equations, working with small chunks of huge data (...

As far as I remember, many ports can be excited in OpenEMS, with the same excitation signal. But how about delaying and attenuating the signal on per-port basis? Particularly, I am interested in driving an array of lumped ports attached to lambda/4 metal probes. Inserting a delaying structure, or a ...

Ok, I had three months simulating a 2x2x2 m space with Tx/Rx antennas and scattering objects. The goal was to analyze a performance of cm wave radar in transition from near to far field, as well as to see the evolution of reflected pulse depending on changing back-scattering conditions. It was reall...

When you define a dump box, you define the data to be dumped, its file name, and storing format. Examine help AddDump() for details. It is quite a complete tool, as you can find, capable of dumping not only rough data, but also subsampling and even extracting a frequency domain components. Define se...

>Noob question:
you should refer to any linux forums, or man. in short, the latter is a better serviced envelope to the former. And the former itself is a satellite tool to apt. so the usage depends on how tricky you are in linux environment.

I do not use KiCAD much, but holding such tool in the pocket sounds great! I just want to ask, how does it create meshlines? using line-edge vertices, or taking 1/3 rule into account for every edge? in between the main coordinates, what distribution do you use? Can important vertex and main edge coo...

Human psychology. When you make it open and free, people try running it on Core2 with 4Gb.... and complain, that "it is raw and resource hungry, while some guy in the lab can make it in HFSS for me" When you sell it for 120 000, people tend to use 5-10% of that budget for presents, including a new g...

isn't phase of the pulse removed when normalizing the frequency response at the output? Then again, if it is a true synthetic Gaussian pulse, why should there be deviations? AFAIK it should be flat as a board.
