[FLASH-USERS] Trying to plot in FLASH with jupyter notebook and pyplot

[Adam Reyes]

Hi,

Yt works well as an alternative to visit for plotting FLASH output. You
should check out their documentation for more information on the
capabilities. The thread you linked looks to be specifically about some
possibly outdated scripts that are included with the FLASH source code. Here
<https://github.com/acreyes/FlashSummer/blob/main/plot_sedov.ipynb> is a
python notebook that shows one way to get the density plot you're
interested in using yt.

In your python script you're only plotting a single block ( the first index
of var), which is probably the root block. Each of these blocks is by
default 8x8x8 cells and is the reason for the apparently low resolution
color maps you're getting. You can read more about how the Grid unit in
FLASH organizes blocks in the usersguide
