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 :)

Fatal Error in exec SCF (LNO-CCSD(T)) was created by chburger
I want to do a LNO-CCSD(T) calculation.

After the HF-SCF successfully converged, the program crashes after the Pipek-Mezey localization step,
during which the following message is printed

Constructing beta Fock-matrix...
 Inverse square root: The matrix is not positive definite!

Shortly after that the program stops with.

Fatal Error in exec SCF

I am using the latest 2020 mrcc binary version with OMP_NUMTHREADS=40 (the machine has 40 cores).

Many thanks in advance!

Regards 

Peter

Dear Peter,

the LNO-CCSD(T) method only works for closed-shell systems and restricted reference determinants in the current (2020) MRCC version.
Open-shell molecules, such as your example, are unfortunately not yet supported with LNO-CCSD(T) in the current MRCC release.
The next release (2022) will include open-shell local MP2 and corresponding double-hybrids but not yet the open-shell LNO-CCSD(T).

Best regards,
Peter
