slfcfd 1.2 file released: slfcfd12.tgz
Science Code Changes *Slightly modified my change to the 2-D quickest algorithm in the incompressible code. *Added streamlines. The input file, named (filename).stream has the same format as pathlines and streaklines. *Added a few arguments which you can pass to the executing code. This is needed for animation. Graphics Code Changes *The graphics code, fdpost, has an animation mode which will both display or save the animation for 2-D flows. Note that you will have to install FFmpeg to save animations.

slfcfd 1.1 file released: slfcfd11.tgz
Science Code Changes *As mentioned before, I have added an incompressible code which uses the 2-D quickest algorithm given by Davis and Moore and which I have modified to keep true upwinding. In addition to being more scientifically true, I think it dramatically improves the results. *Added new boundary conditions for the incompressible code. The most significant new boundary, noslip for obstructions in the flow, has also been added to the compressible code. *Added the ability to calculate streaklines and pathlines. This is true for both the compressible and incompressible code. *In the compressible code, I had to change the way the steps are counted so that now it stops one step less than the 0.75(or 1.0) release. This was done after careful consideration of the way "dt" was added to the time. Slight numerical error would sometimes result in an additional step, so I changed the code such that this error will not affect the results. This changes the previous results though, in that they are often one step less than the calculations of the previous release. Graphics Code Changes *The graphics code, fdpost, can handle both compressible and incompressible data. And it will display the pathlines and streaklines.
