My name is Sanjay Sriram and I am using LAMMPS to study adsorption of water on a mica surface. In order to study this behavior I am employing GCMC that runs for 200000 steps. However I am only able to run 1000 steps and I repeatedly get the lost atoms error no matter what parameter I change. Please let me know how to rectify this problem?
Impossible to say from remote based on such limited information. You obviously have not found the correct settings.
