[Nek5000-users] Full restart with increasing lx (nek5000-users at lists.mcs.anl.gov)

I guess the way to go, if you want to have full restart, is to first 
reduce the time step with the old resolution, save the three restart 
files (in the latest version only three files are necessary for order 
three) with the new time step but old resolution, and then restart...
