Hi Matt, unfortunately, it did not work. I am enclosing my very basic parameter file in case you want to give it a try, Thanks, JC On 29/08/11 16:37, Matthew Turk wrote:

Hi JC,

This is a silly question, but have you tried with removing the .yt file? They can collide if you re-run and get a different grid structure between outputs but you don't wipe your directory. Often this can occur if you are running on multiple processors.

(If that's it, adding a system to invalidate based on the ._hash() of the parameter file would prevent problems like this... would be a good introductory project...)

Let me know if that fixes it,

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: current_time = 0.0001000089999 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() --------------------------------------------------------------------------- TypeError Traceback (most recent call last) /rpod2/jcpassy/yt-x86_64/src/yt-hg/scripts/iyt in<module>() ----> 1 2 3 4 5 /rpod2/jcpassy/yt-x86_64/src/yt-hg/yt/data_objects/static_output.py in hierarchy(self) 167 raise RuntimeError("You should not instantiate StaticOutput.") 168 self._instantiated_hierarchy = self._hierarchy_class( --> 169 self, data_style=self.data_style) 170 return self._instantiated_hierarchy 171 h = hierarchy # alias /rpod2/jcpassy/yt-x86_64/src/yt-hg/yt/frontends/enzo/data_structures.py in __init__(self, pf, data_style) 160 self.float_type = 'float64' 161 --> 162 AMRHierarchy.__init__(self, pf, data_style) 163 # sync it back 164 self.parameter_file.data_style = self.data_style /rpod2/jcpassy/yt-x86_64/src/yt-hg/yt/data_objects/hierarchy.py in __init__(self, pf, data_style) 58 59 mylog.debug("Counting grids.") ---> 60 self._count_grids() 61 62 # Must be defined in subclass /rpod2/jcpassy/yt-x86_64/src/yt-hg/yt/frontends/enzo/data_structures.py in _count_grids(self) 182 self.num_grids = test_grid_id = int(line.split("=")[-1]) 183 break --> 184 self._guess_data_style(self.pf.dimensionality, test_grid, test_grid_id) 185 186 def _guess_data_style(self, rank, test_grid, test_grid_id): /rpod2/jcpassy/yt-x86_64/src/yt-hg/yt/frontends/enzo/data_structures.py in _guess_data_style(self, rank, test_grid, test_grid_id) 185 186 def _guess_data_style(self, rank, test_grid, test_grid_id): --> 187 if test_grid[0] != os.path.sep: 188 test_grid = os.path.join(self.directory, test_grid) 189 if not os.path.exists(test_grid): TypeError: 'NoneType' object is not subscriptable ---------------------------------------------------------------------------------------------------------------------

Could someone help me to fix this ?

Thanks a lot,

JC
