Dear Suni,
It looks like FAST is running as it should.
Unfortunately we don’t have detailed step-by-step instructions for how to make use of FAST. Regardless, a good way to learn FAST is to review the presentations and sample models/simulations that were presented at our last modeling workshop. These are available for FAST v8.08 (not quite the newest version, but I don’t have newer materials that are so comprehensive) in my in my Sep 15, 2014 post in the forum topic found here: Modeling Workshops. After that, I suggest that you study the various user’s guides and theory manuals.
Best regards,
