[yt-users] Issue with hierarchy stats

[Jean-Claude Passy]

Hi all,

I am running a modified TestOrbit problem. If I try to look at the 
hierarchy of the first dump, everything is working just fine:

---------------------------------------------------------------------------------------------------------------------

In [32]: filen1 = 'DD0000/data0000'


In [33]: pf1 = load(filen1)

yt : [INFO     ] 2011-08-29 13:26:58,698 Parameters: 
current_time              = 0

yt : [INFO     ] 2011-08-29 13:26:58,698 Parameters: 
domain_dimensions         = [32 32 32]

yt : [INFO     ] 2011-08-29 13:26:58,698 Parameters: 
domain_left_edge          = [0 0 0]

yt : [INFO     ] 2011-08-29 13:26:58,698 Parameters: 
domain_right_edge         = [1 1 1]

yt : [INFO     ] 2011-08-29 13:26:58,698 Parameters: 
cosmological_simulation   = 0.0


In [34]: pf1.h.print_stats()

level   # grids     # cells

---------------------------

   0          1        32768

----------------------------

              1        32768


t = 0.00000000e+00 = 0.00000000e+00 s = 0.00000000e+00 years


Smallest Cell:

         Width: 1.013e-26 mpc

blablabla....

---------------------------------------------------------------------------------------------------------------------





However, if I try to do the same for a later dump:

---------------------------------------------------------------------------------------------------------------------

In [40]: filen1 = 'DD0001/data0001'


In [41]: pf1 = load(filen1)

yt : [INFO     ] 2011-08-29 13:29:56,004 Parameters: 
domain_dimensions         = [32 32 32]

yt : [INFO     ] 2011-08-29 13:29:56,004 Parameters: 
domain_left_edge          = [0 0 0]

yt : [INFO     ] 2011-08-29 13:29:56,004 Parameters: 
domain_right_edge         = [1 1 1]

yt : [INFO     ] 2011-08-29 13:29:56,004 Parameters: 
cosmological_simulation   = 0.0


In [42]: pf1.h.print_stats()

Could someone help me to fix this ?

Thanks a lot,
