Dear Stefan,


thanks for your checking.

I have some output files of simulation tasks without mgdraw.f performing successfully.

and I compared the output files with one of input with mgdraw.f

it turns out one is running fluka2020, the other one is fluka2010(as shown in below screenshot respectively).

but all the setting procedures are the same for different simulation tasks, I don't know why they are performed in different versions.

how can I make sure $FLUPRO set to fluka2020.

Qi Ding

Dear Qi Ding,

I had a look at the logfiles, and they seem to suggest that you are
runnning fluka2011, but maybe your executable was built with fluka2020?

You should make sure your FLUPRO-variable is set to fluka2020 when
running - now it
looks to me that your executable is trying to access the wrong
"nucear.bin"-file, and since fluka2020 contains more isotopes, it will
try to access more data than is actual in the file it tries to access -
this would explain the message.

At line 120 of file ncdtrd.f (unit = 14, file = 'nuclear.bin')
Fortran runtime error: I/O past end of record on unformatted file

So you should make sure that when you build the executable and when
running it, you have $FLUPRO set to fluka2020.

Cheers,

         Stefan
