You're defining natural Europium as a compound of two isotopes Eu-151 and Eu-153 but you're not giving their mass number.
I am not sure what you are referring to here. I am attaching a snapshot of the MATERIAL and COMPOUND cards for nat Eu. I was missing the mass number for natEu (i.e. 151.96) which I added in after your comment. Is this what you were referring to?
What I'm saying is that the Europium definition should look like this (or the equivalent flair snippet in attachment):
MATERIAL 63. 5.2227 151.Eu-151
MATERIAL 63. 5.29195 153.Eu-153
MATERIAL 63. 5.264 natEu
The atomic number A (i.e. What(6)) were missing from your definitions.
I also believe that there's a numerical issue with your BEAMAXES card.
What kind of numerical issue are you referring to? I can't see it. I've checked the beam distribution and direction and it is what I intended it to be, i.e. the beam is along Z direction with beam Z at 22 deg with respect to the geometry X axis. I am attaching a snapshot of the BEAMAXES card.
I'm sorry, this was due to a small pre-editing I did on your original file to remove all the equations. Therefore, I was left with numerical values only (see attachment).

Helo Lefteris,
I have attached the input file.
This is the first time (in six years) I have seen an error like this. I have checked the material definitions for all materials in the card and none is assigned a density of 0.000 as suggested by the error. If the error did actually point to a specific material (by name or number), then I would be able to track it if.
Let me know if you need the associated biasing files, etc.
Thank you,
Mina

Subject: [fluka-discuss]: STOP INVALID MATERIAL DENSITY
Hello everyone,
I've been trying to track an error in my input file and have been able to pin point it.
There seems to be a material that FLUKA is seeing with a density of 0.00 assigned to it.
Now, I have neither intentionally set a density of 0.000 to any material, nor have been able to find a material in my input file with a typo in the density causing such an error.
All I see in the error file is the following message, without any more info. on where FLUKA is seeing an 'invalid material density'.
Invalid density 0.000 for material
Abort called from PRCHCK reason INVALID MATERIAL DENSITY Run stopped!
STOP INVALID MATERIAL DENSITY
So I am wondering how to go about tracking and fixing this bug?
Any insights would be appreciated.
Thank you,
Mina
