[gmx-users] Error in NVT equilibration step

[banijamali_fs]

Hi there, 

I'm doing simulation with gromacs, in NVT equilibration step when I
insert this command, 

gmx grompp -f nvt_0.mdp -c min.gro -p topol.top -o nvt.tpr 

I get this error: 

Fatal error:
There is no domain decomposition for 48 ranks that is compatible with
the
given box and a minimum cell size of 3.33469 nm
Change the number of ranks or mdrun option -rdd or -dds
Look in the log file for details on the domain decomposition 

Is there anyone who nows what should I do with this error?
