× If you have problems during the execution of MRCC, please attach the output with an adequate description of your case as well as the followings:
  • the way mrcc was invoked
  • the way build.mrcc was invoked
  • the output of build.mrcc
  • compiler version (for example: ifort -V, gfortran -v)
  • blas/lapack versions
  • as well as gcc and glibc versions

This information really helps us during troubleshooting :)

ghost atoms for cartesian coordinates

7 years 4 months ago - 7 years 4 months ago #1 by Amora

I'm running the following input file for O2 dimer (quintet state) with midbond functions (MRCC standalone):
# CCSD(T) calculation for the O2 dimer with aug-cc-pVDZ basis, with ghost He atom


O 0.991599087 0.000000000 -2.177500000
O -0.991599087 0.000000000 -3.322500000
O 0.991599087 0.000000000 3.322500000
O -0.991599087 0.000000000 2.177500000
He 0.00000 0.00000 0.0000


But it gives the following

This molecule is an asymmetric top.
This molecule is planar.

Point group: D2h
Computational point group: C1

Cartesian coordinates in standard orientation [bohr]
1 O NaN NaN 0.00000000
2 O NaN NaN 0.00000000
3 O NaN NaN 0.00000000
4 O NaN NaN 0.00000000
5 He NaN NaN 0.00000000

Nuclear repulsion energy [au]: NaN

What is wrong with my input? The test job for HF dimer is working fine, but there Z-matrix is used.

And I have one more question: is it possible to do ROHF/UCCSD(T) calculations with MRCC?
I would be appreciated for help.

best regards, Yulia

Thank you very much for reporting this bug. It has been fixed and a new version is available.

If you run a CCSD(T) calculation with ROHF reference, an ROHF-UCCSD(T) calculation is performed by default.
