Dear Fluka experts
I am getting some unexpected results when increasing the pressure of a fixed volume of Nitrogen gas.
I am interested in the amount of activation generated in the nitrogen gas. However, when I increase the pressure from 1bar to 10bar (a factor of 10 density increase - 0.0011g/cc to 0.011g/cc) I get a factor of 100 increase in the total activity.
I have tried with and without the MAT-PROP card and set the pressure to 10 bar although this seems to make little difference to the results.
I have attached my input file although this includes lots of other details as I was previously using it to look at the foils separating the gas.
