[FLASH-USERS] column density

[Scott Feister]

Hi Muhammad,

This search of the VisIt user's forum archives might be relevant. It looks
like you can "hack" a column density plot from VisIt's "X-ray" function:

If you are a fan of python, the open-source "yt" module (
http://yt-project.org) is good at making non-interactive projection plots
from FLASH HDF5 outputs. (In the Anaconda python distribution, download
this package via "conda install yt"). For example, this script would take
3D FLASH data and make a 2D colormap plot, where density is integrated
along the x dimension:


*import yt*
*ds = yt.load("my_hdf5_plt_cnt_0000")*
*p = yt.ProjectionPlot(ds, 'x', 'density')*


*p.save()*
Best,

Scott
