Dear Aparajita,
It is strange that the fort.9 unit is empty. May it be a problem of the script in copying back that unit from the scratch folder to the working directory?
Anyway, you can try to trick CRYSTAL in this way:
By inspection of your output file: CYC 13 ETOT(AU) -1.952535840054E+05 DETOT -1.58E-05the energy difference is down to 10^-5 at cycle 13. So, you can try to run the calculation with a low energy convergence threshold of just 10^-4 with something like this:
TOLDEE 4and the SCF would be considered as converged for the program. In this way the calculation is not killed and probably you will get your fort.9 unit,;
you can then use it to do a restart calculation with the GUESSP keyword (and by tightening the energy convergence threshold to something like TOLDEE 7, or 8): GUESSP TOLDEE 7Hope this helps,
