I don't see any mention on these forums other than Rocksim (Apogee, you buy it) and Openrocket (free). Similar functionality. Both are good.

Thrustcurve.org can give you quick estimates based on weight and dianeter of rocket, and will batch run a the suitable motors.

OpenRocket is free and allows most basic rocket geometries to be created. It's CP position is conservative (further forward) because it uses the basic Barrowman equations. By user experience, its results for trans/supersonic flights seem to be more accurate than rocsim.

Rocsim is paid software that can create more advanced geometries (pods, outboards, split bodies, etc...). It expands on the Barrowman equations and loosens the restrictive assumptions, so its CP is generally a bit further aft (less conservative margin).

I've never used it but RasAero is another option. I understand it is very good for extreme sims (>mach1, >50k ft, etc.)

Rocksim has a pretty animation / graphic of your rocket flight..

That's a crazy statement. I use OR myself, but if you want pod and/or tail ring support Rocksim is the only game in town for the moment. Both programs have their advantages; it simply depends on which capabilities are most important to you.
