Hi Eric, perhaps you can help me further about an error message concerning
input to ORCA that is unclear to me
setting in namd conf file about orca:
> qmConfigLine "! UKS BP86 RI SV def2/J enGrad SlowConv"
> qmConfigLine "%%maxcore 2500 end"
> qmConfigLine "%%pal nproc 34 end"
> qmConfigLine "%%scf MaxIter 5000 end"
> qmConfigLine "%%output Printlevel Mini Print\[ P_Mulliken \] 1
> Print\[P_AtCharges_M\] 1 end"
Error shown in /0/..TmpOut
[file orca_main/maininp1.cpp, line 14628]: ERROR: expect a '$', '!', '%',
'*' or '[' in the input
By commenting out the line
qmConfigLine "%%maxcore 2500 end"
the simulations starts regularly. The default mem 1024 gave rise to warning
in /0, while 2500 per core corresponds to less than 75% mem available on
I must have been unable to interpret correctly the Example furnished by
ORCA, or there is something else that I don't understand.
! DLPNO-CCSD(T) def2-TZVP def2-TZVP/C
Thanks for advice
