Dear i-PI users,

I am trying to run i-PI coupled with LAMMPS. The job enters the running state correctly, but even after more than 6 hours of execution, all output files remain empty.

I observe the same behavior when running one of the provided examples. The simulation appears to be running, but no data are written to the output files.

I have attached my input files and relevant data for reference. Could you please help me identify where the problem might be?

Best regards,
Somayeh Ahmadkhani

Hi Somayeh,

Looks like LAMMPS cannot find a file so it never starts really.
In your error message there is:
"ERROR on proc 0: Cannot open file water_qtip4pf.data (src/read_data.cpp:1938)"

Cheers,
