Hello, I am attempting to run a QM/MM simulation with an external interface to Orca. I am able to run it on my machine (albeit very, very slowly). I get the Orca output files and the SCF converges well. However, when I try to run this in parallel (on a supercomputer) I am getting the following error:
SANDER BOMB in subroutine read_results (qm2_extern_orc_module)
Error reading Orca output from file orc_job.engrad
(Current total energy or gradient not found or unsupported units.)
I get a similar response when I try to use qchem with amber. I think Amber and Orca are just not able to communicate like they should, but I am completely unsure as to why. This happens both when I submit the job in a batch script, or on the command line. Any suggestions would be greatly appreciated, thanks for your time.
