Re: [fluka-discuss]: RESNUCLEI error

Dear all

the RESNUCLEI summing routine usrsuw (and also the usrsuwev routine)
require to read the nuclear.bin file to access relevant informations about
residuals (typically half-lives, isomers etc).

Hence they are unfortunately specific of the nuclear.bin version used by
FLUKA when generating "raw" residual nuclei files, and a check for this
purpose is built-in into those utilities. On top of that, there was a bug
in between fluka2021.2.4 and fluka2021.2.5 in those utilities, fixed in
2021.2.5, see the snippet below from the the 2021.2.5 announcement:

- an issue with the residual nuclei summing tool, usrsuw.f, which could
  not work because a call required to retrieve the FLUPRO environment
  variable was missing, thanks to Pavel Degtyarenko for pointing it;

Perhaps it would have been wiser to add that those utilities needed to be
recompiled and relinked against the new FLUKA respin in order to get the
bug fixed. For this purpose it suffices to issue:

cd $FLUPRO/flutil
./lfluka -o usrsuw usrsuw.f
./lfluka -o usrsuwev usrsuwev.f

or in order to get ALL utilities in flutil recompiled/linked:

cd $FLUPRO/flutil
make clean
make

Reinstalling FLUKA from scratch as suggested by Angel surely works, it is
a bit of overkilling but it does the job.
