Clarifies variable names
Removes previous attempt to limit damping moments by using minimum
velocity of 1.0
Clamps damping moments so they cannot exceed actual moments, avoiding
numerical instability
- Fins may be attached to Transitions (and subclass NoseCones )
[Fix] FinSet now implements the Ring-Instanceable interface
[Refactor] Rocket inherits from ComponentAssembly instead of RocketComponent
[Fix][Refactor] Fin tabs are now correctly validated upon change
[Fix] Fin tabs are now corrected to be no-bigger-than their fins
[Refactor] FinSet.getBodyRadius(..) now requires an argument
[Fix] restricted fin tab positioning to be strictly top/middle/bottom
[Refactor] Reimplement FreeformFinSet.setPoint(...)
[Fix] Prevent Freeform Fins movement past parent's top/front
[bugfix] Fins are now addable to transitions from the GUI
[Fix] Fins, Transitions are now drawn correctly in fin-design window
[Minor] Added makeV2 rocket to TestRockets
[fix] getRootPoints() impl & test
as NaN in data export. Fixed.
TODO: the code is very sloppy about naming variables velocity (ie
speed and direction) vs speed (ie magnitude of velocity). Should be
fixed after this release... I started down that rabbit hole a couple
of times before settling on just fixing the actual bug.
sustainer stage, we don't check for tumbling until after apogee, which
is consistent with the email discussion eg
https://sourceforge.net/p/openrocket/mailman/message/32016278/
Not switching to tumbling until after apogee results in unstable
booster stages going into wild oscillations, and firing an exception
terminating the branch of the simulation. This brings the code into
conformity with the comment.
* Fix Average Thrust Calculation (fixes issue #441)
Remove test for short time interval before first data point in thrust
curve. Comment said it was for numerical stability; multiplying by a
small number and then adding doesn't introduce any instabilities I'm
aware of in this code.
Add parentheses to clarify that values are being multiplied by time
intervals, not divided.
* Code clarification; should make no difference to results
* [refactor] fixed warnings and made variable names more explicit in [Freeform]FinSetConfig Dialogs
- de-duped writeCSVFile methods
* [Fixes#424] Respaced FinSetConfig Window:
Resolved some sources of phantom whitespace; Spacing on component configuration
windows is now generally tighter.
* [cleanup] Refactored naming in ScaleSelector to be more consistent 'Zoom' -> 'Scale'
* [refactor] updated BoundingBox class to be more useful
- FlightConfiguration now exposes the BoundingBox method for its rocket
* [refactor] Reduce redundant methods in Scalefigures, and harmonize common function names
- removed interface that was only inherited by the single AbstractBaseClass
- harmonizes the border pixels variables in the scalefigure package
* [rm] excised EXTRA_SCALE (==S) factor in ScaleFigure Code

- auto-zooms on startup
- ScaleSelector Text updates with +/- buttons
- adjusts fin-point drawing code
* [feat] FinPointFigure draws its parent/mounting half-body (w/front & back terminators)
* [fixes#425] FinPointFigure ScrollBars now adjust with zoom in/out
* [fix] clicking away from points now longer causes an exception
* Version Bump to Alpha 8
* [fixes#424] Addes back in ConfigDialog outside spacing.
* [feature][Resolves#426] implemented FinPoint SelectedIndex Indicators
- figure and table update each other
* [fixes#419] Clicking in fin-point figure now calculates closest segment correctly
* [fixes#431] Fins default to instance count / fin count == 1
- Fixed init bug
- added unittests for fin count loading/saving/creation
* [fix] Revert patch 6289aef0... which introduced simulation anomalies

* [fixes#439] May now delete points again, in the FreeformFinSetConfig window
* [fix] AbstractScaleFigure now stores (& requires!) the visible bounds when setting zoom/scale.
- if the visible bounds are larger than the requested scale bounds, then the figure is expanded to match.
* [fixes#436] Rocket figures now center as desired.
* [fixes#425][fixes#440] FinPointFigure contents are bottom-aligned, properly sized.

* Closes 443
When the events STAGE_SEPARATION and EJECTION_CHARGE are both triggered by
BURNOUT, both events occur simultaneously and either can be inserted
in EventQueue first. If STAGE_SEPARATION is inserted first, the
filter in BasicEventSimulationEngine.java ignoring events from
components that are no longer attached to the rocket drops ignores
EJECTION_CHARGE. If second stage IGNITION is triggered by
EJECTION_CHARGE it is filtered out, and second stage IGNITION fails to
happen. This can be seen in the following snippet of a log file:

Note here that there was no IGNITION in the sustainer branch, and the
Thrust is 0.0 at the end of the snippet.
Moving the test for ignition events ahead of the filter assures the
IGNITION is scheduled, as seen in this log file snippet:

Here, the IGNITION does take place, and Thrust is non-zero.
Displaying a plot of the flight, and saving CSV files, shows a normal
two-stage flight profile.
This commit does two things:
(1) adds a little more logging, in particular logging what event has been
obtained from EventQueue and logging when that event is ignored.
(2) moves the motor ignition events test ahead of the filter, as
described above.
* Correct active stages after STAGE_SEPARATION event
* oops, didn't want to keep the extra debugging log entries
* more fixes to stage ignition: now also pays attention to ignition
type and additional delay
