Re: non-uniform how work?

Hi,

sounds like using the cylindrical mesh would be possible in your case.
Please work through the Tutorials at http://openems.de/index.php/Tutorials.

Re: openEMS Documentation

Hi,

xmin is not a point, it is a plane. Consider x = xmin.

To read the manual you need a latex distribution. MikTeX for Windows or TexLive for unix.
Execute

Code: Select all

pdflatex openEMS_UserManual.tex
to generate the pdf document.

regards

Re: Plasmonics and some questions

Hi,

You can add a cylinder of air to your structure. Be sure to increase the priority of this cylinder over the priority of the metal box/sheet.
OpenEMS samples each mesh point and decides according to the highest priority, which material "wins" at this position.

Re: Packages for Debian Wheezy [edited]

Hi, We use the openSUSE build service to create our binaries. Debian Wheezy is not yet present there. Thorsten used a new feature from a recent tinyxml library, which is too old in Debian 6 and Ubuntu Natty. That's why the current openEMS is not yet available for these platforms. To build your own p...

Re: Just a general question - and some remarks !

Hi hwe, the new scilab version is able to read and write xml files. This should make it simple to convert our Matlab scripts to Scilab. The automatic conversion did not work well, by the way. OpenEMS will never be a competitor for commercial software packages, because of the missing support. The req...

Re: Release Notes on openEMS v0.0.30

Linux binary packages have been updated. Ubuntu 12.10 (Quantal) is now supported. Support for Ubuntu 11.04 (Natty) was dropped due to tinyxml being too old. OpenEMS no longer collides with paraview installed from system packages (we abadoned the c++ interface to hdf5 to achive this). Hyp2mat is avai...

Re: Lumped RC element simulation

Taflove 3rd ed. page 711: we need one additional variable to hold the sum of the E-field (voltage in our implementation). Looks like the extension concept would be ideal for the implementation. Anyone?
Edit: this may also serve as a tutorial: how to create an extension for the simulator core.

Re: Lumped RC element simulation

you certainly can: http://de.farnell.com/jsp/search/browse ... allpartial; choose from about 13000 components.

What to fix first: documentation or your code, Thorsten ;)

Re: Lumped RC element simulation

If you run help AddLumpedElement you'll see that this function accepts tho optional argumguments 'R', 'L' and 'C'. A "pure" inductance is therefor possible. Be careful with the word ideal . An FDTD will never report ideal results, the truncation of the floating point numbers will limit the archivabl...
