[FLASH-USERS] Reading data using MATLAB

[John ZuHone]

Hi Graeme,

Unfortunately I don't have that much experience with MATLAB, but I thought I would take a moment to at least say you should have a look at yt:

http://yt-project.org

which is in Python, and already has much of what you'd probably want to do with FLASH data already running out of the box without you needing to apply much effort hopefully. With Python and NumPy together you have something that is pretty similar to MATLAB:

www.scipy.org/NumPy_for_Matlab_Users

(though the SciPy website doesn't seem to be responding at the moment.)

Best,

John ZuHone

I’ve managed to get to the stage where I can read in the data using the HDF5 files and I'm trying to reconstruct the mesh using the /coordinates /block size and /bounding box output, however I seem to be running into the problem that there don't seem to be enough blocks to match that of the resolution that I've been getting when I visualise the data using VisIt, and there are far fewer blocks than I have output data such as /ye. I should probably add that I’ve been using the paramesh 4 option for the mesh construction.
