Assuming you're using LINCS, from the manual: "With domain decomposition, the cell size is limited by the distance spanned by *lincs-order*+1 constraints." Assuming a default lincs-order (4), 0.82nm seems a fairly sane distance for 5 bonds.
Which means that you're probably using too many nodes for the size of your system. Hope that helps. If it doesn't you'll need to provide some information about your system. -Trayder On Thu, Oct 17, 2013 at 1:27 PM, Nilesh Dhumal <ndhu...@andrew.cmu.edu>wrote: > Hello, > > I am getting the following error for simulation.
