[FLASH-USERS] hdf5 puzzle

[Ryan Farber]

Hi Sylvain,

I haven't used FLASH3 before. But I'd suggest using an older version of
HDF5. For reference, I typically use hdf5 v1.8.10. I'd guess for an older
version of FLASH it'd be ideal to use an even older version of HDF5
(ideally what was at use during the time of development).

Best,
--------
Ryan
