i did equilibration with multidir using this command
mpirun -np 21 gmx_mpi mdrun -multidir equ1 equ2 equ3 equ4 equ5 equ6 equ7 equ8 equ9 equ10 equ11 equ12 equ13 equ14 equ15 equ16 equ17 equ18 equ19 equ20 equ21 -deffnm nvt
i tried this command
mpirun -np 21 gmx_mpi mdrun -rerun -multidir equ1 equ2 equ3 equ4 equ5 equ6 equ7 equ8 equ9 equ10 equ11 equ12 equ13 equ14 equ15 equ16 equ17 equ18 equ19 equ20 equ21 -deffnm nvt -nb CPU
but got
Multiple simulations not supported by rerun.
and need to add energy groups and make a rerun for the command but couldn’t find how can I do this . can someone help, please
