[FLASH-USERS] Using FLASH with GDL

[Dean Townsley]

Hi Amol,

I think the more general theme that John is getting at is that the IDL 
visualization tools (fidlr/xflash3) that ship with flash are not as 
widely used as they used to be.

I haven't tried out yt, though it looks quite nice.  But since John is 
mentioning other options I'll mention what I use...

For visualization I use mainly VisIt (http://visit.llnl.gov).  It is a 
little challenging to build, but doesn't depend on anything proprietary 
as far as I know.  It has both a gui and a python interface.  For more 
serious analysis I generally use quickflash 
(http://quickflash.sourceforge.net) to handle working with flash data 
files in C++.

Just adding to the conversation.  I should try out yt at some point.

Dean
