Flow Advanced Simulation Tool

The FAST software includes the following key features:

unified conservative formulation for bounded/free flows in natural coordinates
self-generated flow-adaptive orthogonal curvilinear grid
coupled fluid physics: production, transport, relaxation, rarefaction
continuous multiscale space/time evolution from nose-to-tail and ground-to-space
general applications: engine, nozzle, body, plume wake, vent, cloud, trail
