Dear users,

    Since I'm already 0 for 1 today, I thought I'd also ask about this error I've seen. I'm trying to get the time series of momentum density in the x-dir from a simulation in FLASH where I have both the plot and particle files with:

############################################################

ts = yt.load("/home/josh/amuse-svn/src/amuse/community/flash/SinkMomTest2/SMT_hdf5_plt_cnt_0??[!0]",
             particle_filename='/home/josh/amuse-svn/src/amuse/community/flash/SinkMomTest2/SMT_hdf5_part_0??[!0]')

times = []
Mom_x = []
Mom_y = []

for ds in ts:
   
   
    try:
        ds.add_field("total_px", function=_px, units="kg/s/m**2")
        ds.add_field("total_py", function=_py, units="kg/s/m**2")
    except:
        continue

    dd = ds.all_data()

    Mom_x.append(dd["total_px"])
    Mom_y.append(dd["total_py"])
    times.append(ds.current_time.in_units("Myr"))

###########################################################

But this gives the error:

IOError: /home/josh/amuse-svn/src/amuse/community/flash/SinkMomTest2/SMT_hdf5_part_0??[!0]

Unfortunately the FLASH frontend is gobbling the error h5py is raising here.

A quick way to get the real error from h5py would be to replace "raise IOError..." on line 208 with just "raise" and then rerun the script.
