zero awp values for non photon particles in MF6 cause HEATR crash #144
Comments
The issue occurs in the df function (line 2004 in the heatr.f90 file) which is used to calculate damage energy. The division by zero occurs in the following lines (line 2030-2031): denom=(zr**twothd+zl**twothd)**threeq*ar**onep5*sqrt(al)
fl=c2*zr**twothd*sqrt(zl)*(ar+al)**onep5/denom The value of ar appears to be zero for a non photon secondary particle, these values are read directly from the evaluation. The evaluation in question appears to have zero atomic weight ratio values for some of the MF6 subsections. This appears to happen for the following MTs and particle subsections in MF6: |
A branch was created (https://github.com/njoy/NJOY2016/tree/fix/tendl-zero-awr) to detect this issue in the future and to make NJOY exit gracefully. As this is an issue related to an error in an evaluation, we cannot fix this problem. I'll do a proper pull request next week. @jchsublet You may want to take note of this one. |
@whaeck I will thank you but you may also take this to the true evaluator(s) for B010 and B011, much nearer to you, as they are copy of ENDF/B-VIII.O in TENDL-2017, and TENDL-2019 |
The original issue said Be10. Are we talking about Be10 or B10? |
All,
There seem to be two different threads on this topic. Below is what I
sent out on the other thread a few hours ago ...
"
All,
Wim's (and Mike's) email points to TENDL-2017 Be10, not B10. I've
checked these subsections and agree that its an evaluation file error. See
the attachment where I've pulled out the relevant lines where outgoing
particles are defined. It seems like residuals up to 4He are ok but
heavier residuals in these subsections have the bad awp=0. This is not an
issue with TENDL2019 10Be as none of these mf6 subsections are present in
that file. I haven't checked the other files noted by Mike, nor have I
checked whether the issue has made it into the other TENDL-2019 files.

@paulromano Mea culpa Be isotopes it was an no B !! and for Be10 and Be11 TENDL-2017 MF6 is incorrect as Skip pointed out, but then my very similar HEATR sequence did not crashed, having said that division by 0 and FFLAGS have a said in the matter. So the for the above the files, the evaluation are at faults, definitely As TENDL-2017 has just been superseded by TENDL-2019 (That's include quite a few format correction) I have checked the above input2.txt sequence with NJOY2016.53 and its works without crashing for TENDL-2019, Be010, Be011 and CO14. More complex HEATR sequences were achieved in the production of the Ace-TENDL-2019 library. |
This will now be detected in NJOY2016. |
It was brought to our attention that a division by zero occurred in HEATR with the Be10 evaluation from TENDL2017:
This can be reproduced with the following ENDF file and input file:
input2.txt
n-Be10-tendl2017.endf.txt
The text was updated successfully, but these errors were encountered:
