Dear FLUKA experts,
I tried to run FLUKA with the following settings
- redefined a material HYDROGEN with high density (0.6 g/cm3) as the target
- incident particles are 12C
- using LAM-BIAS to consider only inelastic nuclear interactions
However, if I set the kinetic energy of 12C to 0.01 GeV, and consider 10000 incident particles, errors occurred, shown as
Abort called from DEUSEV reason NP/=0 before NUCEAZ. Run stopped!
STOP NP/=0 before NUCEAZ.
But no errors when I changed the incident particle number to 1000 with 0.01GeV.
ALso, no no errors when I changed the incident particle number to 10000 with 0.1GeV.
I have attached the inp file.
Anyone knows what happened?
run.inp (1.5 KB)
Anyone can help me?
Thanks in advance!
Dear Kaiwen Li,
We are looking into it. It is a legitimate bug (12C picking 2H as target isotope, going to inverse kinematics, and doing a 2H on 12C interaction which crashes). Further tests are now underway. Stay tuned.
With kind regards,
Thanks a lot for your response! Looking forward to your results.
One more question, in the above situation (C-H inelastic nuclear interaction, 0.01GeV for 12C), the ratio of the produced alpha particle is about 0.89 per reaction. However, when I used Geant4 to simulate the same interaction, the ratio of alpha particle is 0.
Does it come from the physics model difference?
I believe that with the new Fluka release your problem should have been fixed.
Thanks a lot!
