Re: Raspbian OS 64bit build. Nearly, but not quite!
So, the thread I didn't want to necro contained some answers towards this. Basically the vtk errors aren't going away but it's the conditional flags catching an unsupported architecture that's the issue to start with. Once you allow for an arm architecture, it seems to build without complaint, altho...

Re: TinyXML becomes a big problem
Hi, I have an Ubuntu 18.04 machine with openEMS on somewhere - I will try and dig out the tinyxml version when I'm on there next. Once I got going, I have never had a problem following the "fresh install" of all the dependencies before an openEMS install on an x86 machine.

Re: Raspberry Pi Cluster - could it run openEMS?
Hi, kdv , I firstly wanted to say thank you and sorry for not saying thank you earlier. I hadn't seen your posts for some reason until I returned to this topic this summer. I have tried your patch and can get it to build successfully. I tried a basic example, based on the patch antenna example, that...

Raspbian OS 64bit build. Nearly, but not quite!
Hi everyone, Rather than necro this thread which I started last year, the recent release of a Raspberry Pi OS 64bit beta and the recent progress on booting pi4 from USB3.0 means I thought it would be worth trying again. I have hit some errors in make (having avoided the issues I worked around in the...

Re: PCB Antenna Simulation
start = [feed_start(1) -substrate.length/2 + gnd.length substrate.thickness]; stop = [feed_stop(1) -substrate.length/2 + gnd.length + 0.1 substrate.thickness]; [CSX port] = AddLumpedPort(CSX, 5 ,1 ,feed.R, start, stop, [0 1 0], true); There doesn't seem to be any Z dimension here - a 2D feed? Shoul...

Re: RF Energy levels at a given plane/surface offset from conductor
Thanks for your reply Thorsten, is there a section of the examples or Wiki I should be looking at for this topic, especially getting SAR or processing the field dumps to provide insight? If I have a given output power and frequency at the feedpoint, I want to calculate the absorbed power passing thr...

RF Energy levels at a given plane/surface offset from conductor
Would it be possible to calculate the radiated EM energy at a distance close to a conductor across a given surface? I'm thinking for specific absorbtion rates. Is this nearfield calcs if we are looking at the distance of the plane from the conductor < lamba/10 or even < lambda/100? I know that we ha...

Re: Error installing on Ubuntu
~$ sudo apt-get install libvtk7-dev
If that doesn't work, use a package manager

Re: Error installing on Ubuntu
http://www.openems.de/forum/viewtopic.php?f=2&t=652 You seem to have the same problem as many people who are following the online instructions (which seem out of date). If you install vtk7 instead, then you should be fine. If you don't feel comfortable with installing from the command line, you can ...

Re: Batches - how to distribute and manage for best performance
Thorsten, thanks. With the patch antenna example it could be the small size of the simulation. I have found the "command" string in FindSsh.m and can see that's the key to managing remote processing. I think I have the basics of two different ways to manage the remote processes - one based on number...
