Subclassed phases

[robfalck]

Summary

• Removes deprecated ODEOptions.
• Version bumped to 0.15.0 due to removed deprecations.
• The cannonball example for the docs now uses a subclassed phase which allows us to couple the phase to a specific ODE class and provide default options (units, targets, rate sources) for the states associated with that ODE.
• Refactor of Phase so that user_*_options and *_options no longer need be be rectified at setup time by finalize_options.
• add_state, add_control, add_polynomial_control, add_design_parameter, and add_input_parameter now have corresponding setup_state, setup_control, setup_polynomial_control, setup_design_parameter, and setup_input_parameter methods. The add methods will explicitly add the named variable to the appropriate container, while the setup methods will raise if asked to set the options of a non-existing variable.

Related Issues

• Resolves Allow add_state to be called in the setup method of Phase #259

Due to some limitations we currently do not allow optimal control variables to be added during setup. Instead it can be done during initialize. However the intent of #259 was to allow for the subclassing of Phases to reduce the amount of option inputs that need to be repeated, and this meets that need.

Status

• Ready for merge

Backwards incompatibilities

The previously-deprecated ODEOptions no longer exists.
