Re: openEMS & Octave

Hi Georg, so far I don't see any problem, you just need to continue with steps 8-11) This is loading some Tutorial into the GUI Octave Editor and "Run" it. You can integrate the Editor into the Main GuiOctave by dragging it on the Main Windows. You use WinXP ? Of cource you can also just edit the m-...

Re: openEMS & Octave

Hi,

Re: openEMS & Octave

Hi, I'm sorry to hear that this is so frustrating. I can't quite make out where the problems have their root. So maybe I just write down what steps I just took on my Windows Notebook. 1) Download openEMS, Octave 3.2.4, Gui Octave 2) unzip openEMS to D:\openEMS 3) Install Octave, just accepting all d...

Re: Field at one point, and FFT

Et = a.TD.values{4} will give you a 4-dimensional array for the fields at timestep 4. Than you can access the data like this Et(ix,iy,iz, comp) ix,iy,iz are the coordinate indices and comp is 1,2 or 3 for the x,y or z component I agree this needs more documentation inside the ReadHDF5Dump help. rega...

Re: openEMS & Octave

Hi, you may also want to have a look at Gui Octave ( http://sites.google.com/site/guioctave/ ). It is a nice graphical front-end which makes using Octave much easier. Keep in mind that Octave is kind of a free alternative to Matlab. It uses the Matlab Syntax etc. That's why the Matlab-Interface of o...

Re: Cylindrical resonator

Hi Manuel, I don't see why this shouldn't be possible. You have to think about how to excite the cavity and in case of an empty, closed cavity, the energy may never decay so you may have to abort at some point and use something like harminv http://ab-initio.mit.edu/wiki/index.php/Harminv In case 3. ...

Re: Field at one point, and FFT

Hi, please have a look at the help for AddDump. If you use FileType 1 you will get a hdf5 file dump, which you can read with Matlab using ReadHDF5Dump. You may want to look into the help for ReadHDF5Dump as well. ReadHDF5Dump can also do a DFT so you can access time-domain fields and/or frequency do...

Re: lossly material

I am hurry to see the implement of Drude model, and the LaTeX book of function. Drude model is already included for a long time ;) Take a look at "examples/other/Metamaterial_Plane_Wave.m" in the openEMS folder... But so far it is only the lossless model... maybe soon I will add the losses and make...
