But in the tutorial of  free energy circulation of methane it use "nstdhdl                  = 10" and nstcalcenergy is used default, while the default nstcalcenergy is 100. I am little confused why in here the nstdhdl is not a multiple of nstcalcenergy. Can anyone help, thanks a lot.

I wrote the tutorial a long time ago, and IIRC 10 was the default at that time. 
  I need to update that tutorial for more recent versions.  In any case, 
nstcalcenergy should be reset if any of the pertinent values are lower (i.e. 
grompp should tell you that nstcalcenergy is being reset to 10 in this case).
