I am not sure the importance of Margin value while running a PBC simulation.
My cell basis vectors are around 100 for each of x y z and when I keep margin =2.5 the simulation runs quite welll but when I remove the margin from the config file ,I get an error after some time into the simulation which says something like "the grid patch has become too small etc. etc. "
What role is the Margin playing here?
What does Margin do?
