Hi there, 

when I type the command 

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

and in continuation, this command: 

gmx mdrun -v -deffnm nvt 

I get this error: 

There is no domain decomposition for 24 ranks that is compatible with
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 

Could anyone precisely explain me what should I do? and explain me about
the numbers and the abbreviations that have mentioned in this error, I
don't understand anymore from this error.
