[yt-users] error when analyzing flash data

[Cien Shang]

Hello, all,

I am a rookie in yT, and am trying to analyze some FLASH data with yT. The
data load process encountered an error which reads:

>>> from yt.mods import *
>>>pf=load("flash_data")
yt : [WARNING  ] 2012-03-18 21:39:56,039 Setting 1.0 in code units to be
1.0 cm
yt : [WARNING  ] 2012-03-18 21:39:56,039 No time units.  Setting 1.0 = 1
second.
yt : [INFO     ] 2012-03-18 21:39:56,039 Parameters: current_time
   = 5.0538751323e+15
yt : [ERROR    ] 2012-03-18 21:39:56,039 Missing domain_dimensions in
parameter file definition!
yt : [INFO     ] 2012-03-18 21:39:56,040 Parameters: domain_left_edge
   = [ -3.08600000e+24  -3.08600000e+24  -3.08600000e+24]
yt : [INFO     ] 2012-03-18 21:39:56,040 Parameters: domain_right_edge
    = [  3.08600000e+24   3.08600000e+24   3.08600000e+24]
yt : [INFO     ] 2012-03-18 21:39:56,040 Parameters:
cosmological_simulation   = 0.0
yt : [WARNING  ] 2012-03-18 21:39:56,040 Setting 1.0 in code units to be
1.0 cm
yt : [WARNING  ] 2012-03-18 21:39:56,040 No time units.  Setting 1.0 = 1
second.

I guess to fix it, I'll have to insert the domain-dimensions into the file.
but I am not sure how exactly to do it. i opened the file with IDL, and the
data are 4 dimensional matrices, something like [16,16,16, 40**]. does
anyone know what went wrong, and how i could fix it?

Your help will be greatly appreciated!

Many thanks,
Cien
