Hello,
I am attempting to use the read_dump command in python for finding the potential energy of the system using a new potential using the 11Aug17 version of lammps. I can get the script to work when running from a straight lammps script, but when I attempt to run the same thing in python I get a segmentation fault, the first few lines of error output are shown below.
The error message only appears when I use the following command in python (when typed into a lammps script it works fine),
lmp.command(“read_dump custom.dump 10 x y z purge yes replace no add yes”)
The command also works as long as the add yes is not attached, but this is crucial in updating particle positions.
