Hi Hua: I'm also not so familiar with h5 file but I can only give you a few suggestions: I haven't try to output a 4D data, even a 3D data. How can the data be organized? You can use -x <ix> -y <iy> -z <iz> -t <it> to specify the particular slice of the whole data, see the h5totxt manual. And, maybe a bash script with for-loop and use '>' to append all slices of data to one file. A better way could be using hdf5 C++ interface to handle the data, you may need to see http://www.hdfgroup.org/HDF5/Tutor/h5lite.html for detailed examples. It can input the data from h5file to multi-dimension array and go on your process.

To: [email protected] Message-ID: <[email protected]> Content-Type: text/plain; charset=ISO-8859-1; format=flowed Hi everyone, I am modeling a continuous plane wave incident on a structure. I want to extract the amplitude instead of instant field and put it into a contour plot. To get the amplitude I can use the maximum value of the field. Since I am not familiar with hf5 files, I want to convert it to plain text and write a program to get the maximum. Can anyone point out how h5totxt output 4D data? Or is there any better way to get the field amplitude and plot it? Thanks, Hua ------------------------------ _______________________________________________ meep-discuss mailing list [email protected] http://ab-initio.mit.edu/cgi-bin/mailman/listinfo/meep-discuss End of meep-discuss Digest, Vol 44, Issue 17 ******************************************** _______________________________________________ meep-discuss mailing list [email protected] http://ab-initio.mit.edu/cgi-bin/mailman/listinfo/meep-discuss
