[FLASH-USERS] Using FLASH with GDL

[Amol Holkundkar]

Hi John,

My knowledge of FLASH is just 2 days old, so in view of this I was considering the usage of GDL of which I had a prior experience though not extensive but basic.


Keeping in mind the suggestions from other users too, I think its now time to learn python and yt.


Just a query, is yt can replace the need of gnuplot, if so then it would be great incentive to learn.

Cheers

Amol,

I am not sure why it does not work with GDL, but I encourage you to check out the yt project, which is an analysis toolset for AMR data such as FLASH. It is Python-based and much more powerful and straightforward to use than the fidlr tools. 

http://yt-project.org

I know it may require learning some Python, but in the long run it is very much worth it. There's lots of documentation on how to do some basic things and it handles FLASH data very well. 

Best,

John ZuHone
