Here is a summary of the updates as of 7/3/08:

Version 1.2 is here.

You can get it at the download page. I have added animation for 2-D flows as well as streamlines. Here is a list of the changes:

Science Code Changes

I made a slight modification to the change I made to the quickest algorithm of version 1.1. This only causes a small change in the results for the incompressible code.
Added the ability to calculate streamlines. This is true for both the compressible and incompressible code.
There are new arguments which you can pass to the science executables. This applies mainly to animation.

Graphics Code Changes

The graphics code, fdpost, will also animate a flow in real time as well as generate frames for saving the animation (if you have FFmpeg installed. You can get it at http://ffmpeg.mplayerhq.hu/).
To save an animation, I added the code ffanim, which depends on FFmpeg to compile and save frames generated by fdpost.

Data Changes

There are no changes to existing data file formats. For animation, there are 2 new files, "fdview.anim" and "anim_name", not including the data generated and removed during animation. The only file you probably have to deal with is "fdview.anim". This is a file you generate when you position the view of the mesh. The last lines of this file are the quantities you want to display such as pressure or temperature, pathlines or streaklines.
