I’m trying to calculate the lift from a fin as a function of airspeed and angle of attack.

I’ve looked in the component analysis section of OpenRocket, but didn’t find what I and looking for.

What tools are out there?

That will depend greatly on the airfoil. I think the sims don't do much with that and just determine a coeeficient of normal force as a function of angle of attack (alpha).)

Barrowman of course has an analysis.

You may want to check into model airplane software as wings generate lift, fins do not (at least fins usually don't).

Fins do - that’s how they steer. But in this case, I’m trying to estimate resistance to roll.
The roll analysis in OpenRocket has a Ci. I wonder if that’s the correct term, estimated, since Open rocket doesn’t know it’s a diamond airfoil.
