[gmx-users] There is no domain decomposition for 16 nodes that is compatible with the given box and a minimum cell size of 0.826223 nm

Hello,

I am getting the following error for simulation. I am using Gromacs
VERSION 4.5.5 and running on 24 processors.

Should I reduce the number of processor or the problem is in bonded
parameters. If I use -nt 1 option. I could run the simulation.

Fatal error:
There is no domain decomposition for 16 nodes that is compatible with the
given box and a minimum cell size of 0.826223 nm
Change the number of nodes or mdrun option -rdd or -dds
Look in the log file for details on the domain decomposition
