Broken workflow for ROHF-CCSD

3 years 8 months ago #741 by SBehnle
Dear mrcc developers,
i'm currently trying to run a canonical CCSD calculation on top of a ROHF reference.
The calculation however crashes as soon as uccsd is called.
The error message is
forrtl: No such file or directory
forrtl: severe (29): file not found, unit 918, file /mnt/home/behnle/WJobs/RO-REMP/testcalcs/MRCC/H2O+/abcdaa1

Judged from the output it seems to me that ovirt does a transformation for restricted orbitals when i select scftype=ROHF and ROHFTYPE=standard but dmrcc then calls uccsd which expects other integral files.
The calculation however works when i select semicanonical orbitals. It also works when i select ccprog=mrcc.

The full input and output for the crashing calculation are attached.
Am i doing something wrong?

PS originally, my plan was to run non-RI MP2 calculations ideally both with semicanonical orbitals and iteratively with standard ROHF orbitals but according to the manual, this seems to be impossible.

Dear Stefan,
I cannot reproduce this. With the version you use rohftype=semicanonical is set by default, and the calculation runs smoothly. Probably you mix various mrcc versions.
Anyway, if you set rohftype=semicanonical, you should avoid this problem.
Please note that MP2 with standard ROHF orbitals is not possible.

Best regards,

Dear Prof. Kállay,
thanks for the extremely quick answer.
You were right on the potentially mixed mrcc versions, that's pretty embarrassing.
Anyway, what still does not work is when i set ccprog=ccsd and rohftype=standard.
Is this supposed to work at all?
Best regards
Stefan Behnle

PS if rohftype=semicanonical is the default, p. 118 of the manual needs to be updated IMHO
