Dear LAMMPS users,
Hi.
I tried to use a restart file from an old LAMMPS package (lammps-3Mar20) to the new version (lammps-29Sep2021) but I got an error message regarding to the “fix shake” command:
ERROR: Shake cluster of more than 4 atoms (…/fix_shake.cpp:868)
When I use old versions of LAMMPS this error disappears!
Can you please let me know what the problem is?
Best,
Saeed.
