Some a problem with the EOS calculation
-
Hello, I'm trying to calculate the bulk modulus of elasticity for a solid. I'm entering the following part of text in a *d.12 file:
...
EOS
RANGE
0.99 1.01 3
PRANGE
0 10 5
END
....
DFT
PBE
END
TOLINTEG
7 7 7 7 14
TOLDEE
9
MAXCYCLE
200
SHRINK
6 6
FMIXING
70
PPANThe calculation results return an error:
" ERROR **** SCF **** SG_IRR ALLOCATION ERROR: ALREADY ALLOCATED"Could you tell me what's wrong and what to do?
Thank you. -
Hi Aleksand,
Can you post the full output file? I just want to check in which step the error is generated. -
Dear Giacomo,
Thank you for your quick reply. I am attaching the output file:

Hi Aleksand,
We investigated the error you encountered. It was caused by a bug in the EOS option, which has been fixed in CRYSTAL23. Unfortunatly, there is no simple workaround available in CRYSTAL17.What I can think about is to manually perform the volume-constrained geometry optimizations in separate runs and then interpolate the results manually.

Thank you very much for your attention to this issue! I'm glad it's not my understanding that's wrong. I've already begun implementing your proposed approach.
