Hello Saranya,This error means that during the nvt equilibrium high forces occurred that made it impossible to resolve the bond constraints. The very high forces occurred most likely are due to some high tension in the system. As indicated in the error message you can. Reduce the time step of your run initially to relax the structure first. Check the output PDB structure at the site where the error occurred (atoms 217 and 218), possibly removing or displacing the offending water molecule manually. Check that you used a well relaxed structure from energy minimisationBest, Christian
