You will probably want to download the users manual for Panair and you can find a link to it on the references page.
This program first asks for the name of the input file. This must be a file written to conform to the PanAir user guide. After calculating the solution, the program produces a file called panair.out that contains a wealth of information concerning the flow problem to be solved. You need to read the user guide before you try to interpret the output.
One little gotcha associated with this program is that it will not start if there are left-over files from a previous run -- and it leaves a lot of debris behind. This is done deliberately because the program has a restart capability allowing it resume calculations at a checkpoint without starting over. This was an important feature in 1978, but somewhat quaint today. There is a command file called clean502.bat that will delete all of these files. There is an alternate file called clean502.sh that does the same job for Mac or Linux folks.
