[FLASH-USERS] output files: Getting started guide?

[Ryan Farber]

Hi Joe,

8x8 refers to the number of cells per block.
The 53 probably refers to the number of blocks.
Additional details might be in the FLASH user guide.

I'd recommend just using yt. yt is for analysis as well as visualization.

Best,
