[FLASH-USERS] xflash is crashing

[George Jordan]

Hi Vincenzo,
 	I would suggest using the visualization software called VisIt. You 
can download it at

 	http://www.llnl.gov/visit/

 	They have worked with us and support the FLASH data format. It is 
a very nice piece of software and I highly recommend it. Its capabilities 
are far superior to IDL. You should give it a try. When launching from the 
command line type:

 	visit -default_format FLASH

to tell VisIt to use the FLASH file reader plugin.

Best,
Cal
