v1.0.2

[jkirk5]

v1.0.2 is now live! This update contains a variety of bugfixes and feature additions

Version Summary

New Features

• New atmospheres for other planets. Mars and Venus are currently supported. Gravitational constants for these planets are also set via the atmosphere selection, however please note that we have not finished testing that gravity is being properly adjusted throughout all of Aviary.
• The dashboard now has a new tab that lists all of the options used inside the Aviary model. This is useful for debugging and verification that options were set to expected values.
• The pre-mission and post-mission groups now share a common class, instead of being separately defined groups
• Seat width and pitch for each passenger class are now exposed variables that can be set by the user, instead of previously hardcoded values.

Bugfixes

• Fixed a bug where the FLOPS-based engine mass component was applying scale factors to the wrong engines in some cases when using multiple engine types.
• Fixed a bug where custom engine models using the needs_mission_solver flag were not being appropriately placed inside the solver group of mission ODEs.
• Fixed a bug where GASP-based mass was improperly handling aircraft with a mix of both fuselage- and wing-mounted engines.
• Fixed a set of GASP-based components that recently broke when attempting to use multiple engine types.
• Fixed a bug where variables that are expected to be a vector, but are not defined by the user via input file or directly setting initial values, would get defaulted to the incorrect shape and cause an error.

Non-backwards compatible changes

• Aviary's constants have been completely overhauled. A single set of constants has been selected, removing the parallel FLOPS- and GASP- based values.
• Ambiance has been removed as a dependency (was previously used for a single external subsystem example case, which now uses Aviary's built-in atmosphere component)
• The val argument was removed from the helper functions add_aviary_input() and add_aviary_output(). For more details please see issue Any custom defaults set in components are overwritten by metadata defaults #1196
• Linking variables between phases has been refactored from custom code for each variable to a generalized approach. It is possible your results may slightly differ due to small scaling changes or changes in the variable linkages. Phase info dictionaries now support new keys to set if time/states/controls should be linked via connection or constraint.
• The energy-state landing group was updated to no longer assume sea-level altitude, which may change results.
• A large number of variables have been changed from options to inputs inside the OpenMDAO components. This causes no changes to the actual analysis, but means that if users have scripted manually setting options in their problems they should double-check those variables are still options (see the metadata option flag).
