Dear Gromacs users,
I am running simulation of apo  protein. In minimization step when I am running this command    " gmx mdrun -v -deffnm em"  the error appears that 
" Fatal error:
There is no domain decomposition for 24 ranks that is compatible with the given box and a minimum cell size of 3.96993 nm
Change the number of ranks or mdrun option -rdd ".
Kindly give your valuable suggestions for handling this error.
Kind Regards,
