A friend asked me if FW can be used to experiment with
different shaped objects dropping through the atmosphere. The idea
is that air density changes as you come down from very high
altitude (25+ miles). Drag, terminal velocity, surface heating,
etc. change as the object drops closer to the surface.
If possible, how would one setup such a simulation?

that can be done using the external analysis with variable density dependent on time / altitude... but with the thermal effects that is pure bit complicated
Or, there were some articles about object - through - viscous environment passing (probably in ANSYS, I can't remember). Look for them and find what you need.
