Re: Assignmat error

Carl,

You just need to do a small adjustment to your MATERIAL definition. In the
SDUM card you wrote HYDROGEN starting in the third character of the field,
so probably FLUKA is reading something like ' HYDROG'.
If you fix that it will work.

I have attached the input file if you could take a look and help me figure
out the problem. Thanks!

I forgot to ask, is there a way to change the density that would make this
work? Without the MATERIAL card, I feel that the change in density is not
possible, but again, I get that error when I try implementing it.

Hi Fluka Team,

Still very new to FLUKA here. I'm trying to understand the cross sections of
p-p collisions from galactic cosmic rays on the galactic gas. I assume it's
because I'm not getting any collisions from the gaseous hydrogen. In this file,
I don't have a MATERIAL command, but I do have an ASSIGNMAT calling hydrogen.
This file ran but I received zero energy deposition in the track-length binning.
When I tried to input a MATERIAL card for hydrogen with a new density and atomic
weight (that of liquid hydrogen), the error file reads,
"****unable to resolve name element HYDROGEN in card****... ASSIGNMAT HYDROGEN regBE3".
Can you explain why this is happening? Thank you for your input in advance.
