[Nek5000-users] box parameters must kept unchanged when using restart utility?

Hi, nekers

I am running the restart utility. And I found that when I change both 
the box parameters (nelx,nely,nelz) and the SIZE parameters (lx1, ldx) 
for the restart run, the computation got stuck and failed at reading  
the filed result files of U and P, like this:
------------------------------------------------------------------------
  set initial conditions
  Checking restart options: turbChannel0.f00009
  nekuic (1) for ifld            1
  Reading checkpoint data
        0       0 OPEN: turbChannel0.f00009
  byte swap: F   6.54321003      -2.93127722E+35
--------------------------------------------------------------------------

Again I follow exactly the tutorial and kept the same set-up in the .box 
file and just increase the element order (lx1, ldx), and now the restart 
works fine.

so .box parameters must kept unchanged when using restart utility? 
right? I just want to confirm that.

Thanks:-) ,
