I am trying to start a run using domain decomposition on a 5x5x10 nm box with about 26,000 atoms in it. I've tried running 8-16 pp nodes, but gromacs always throws an error saying that there is no domain decomposition compatible with this box and a minimum cell size of 6.728 nm. I've tried many values for -dds and a few dd vectors, but with no luck. Does anyone know to get domain decomposition working on a rectangular system like this?<div>
