ff6b23f366 merge integrateInertiaVolume() into integrate() 2023-11-21 16:40:57 -07:00

4b1c6a4f4b eliminate SymmetricComponent::integrateInertiaSurface() 
Previously, the code calculated the volume of a component, and if that volume was too small calculated its moments of inertia based on the surface instead of the volume. The decision wasn't based on the thickness of the shell (which might have made sense to me), it was the actual volume. The result is any really small component had its moments of inertia calculated using this surface method, no matter how "solid" the object was.

The cause of #2403 was that this method was used to calculate the moments of inertia in the .ork that failed, but the actual CG was used in the parallel axis theorem. This put the CG in a different place than a "surface CG" would have, so the longitudinal moment of inertia ended up less than 0 triggering the crash.

Now, if a component is so small that's volume is 0 it is assumed its contribution to moment of inertia must also be negligible, so the moments of inertia are set to 0 in this case.

9fec2af7a8 Use Double.NaN to identify values that haven't been calculated. Spotting uncalculated values by checking for <0 is just asking for trouble down the line. 2023-11-21 15:54:35 -07:00

Also, existing code wouldn't call calculation post-listeners if pre-listeners had been called. Fixes that.

7a2ede6e24 Use current atmospheric conditions, not previous conditions, in calculating thrust. 
This lets us get rid of previousAtmosphericConditions completely.

Note that while we pass acceleration and atmospheric conditions into calculateAverageThrust(), we don't actually do anything with them there. They appear to be passed in for some sort of eventual enhancements when we do things like altitude compensation for motors, or acceleration for hybrids or water rockets.

It also turned out that while we called getPreviousAtmosphericConditions() when call ing calculateAverageThrust(), setPreviousAtmosphericConditions() was never called.
