Runs can be extended with -extend, -until, or with -nsteps. If you don't apply any of those, then yes, the number of steps in the .tpr file is maintained.

Or should I just define the time anyway ?


If you don't, your run won't do anything.

Thank you. I was just reading that as well, but didn't realize it could also be 
used to extend. I thought it was just runs that terminated early.

Dear advanced users,

I'm trying determine the procedure for extending NPT run (i.e I realized the 
NPT run I did wasn't long enough, so I wish to run it for another million 
steps. ) what should I do to set up the run again continuing with the previous 
data?
