Dear Gromacs users,
Good someone give me a hit about the following issue. I am running a system which contains few periodic molecules (graphene sheets). Everything was running fine when the simulations were performed using group cut-off scheme and GROMACS 4.5.7. However, when I tried to transfer the same system to 5.0.4 version and switch from group to Verlet scheme the run crashed with the following error:
"There were 80 inconsistent shifts. Check your topology"
No changes in topology files were performed. The difference in MDP files between two cases is shown below. Am I doing something obviously wrong?
Many thanks in advance,
Mikhail
