particular file to the directory where you are running the ./flash4
executable. If you are running the executable in the *object* directory
where you have configured and made it, then the default Simulation module
for the *LaserSlab* problem will have not moved that particular file there.
You can change this by editing the *Config* file. For instance, I can see
that in my version of the *LaserSlab* problem, it will only copy these
files to the object directory:

DATAFILES al-imx-002.cn4

DATAFILES al-imx-003.cn4

DATAFILES he-imx-005.cn4
e.g. Tables for aluminum and helium as found in the *Config* file in
*/source/Simulation/SimulationMain/LaserSlab/*

from my naive experience, I've never heard of someone doing that in a
Eulerian fluid code but I am sure I one can google it if it's been done.
However, if you want to do standardized extractions of the species you're
using as materials in FLASH, as well as acquire information such as the
electron and ion densities, make sure you're using 3T and take a gander at
page 539/section 34.7 of the user manual.
