Summary

In support of upcoming changes, it made sense to treat t_initial and t_duration as parameters that are always present in the ParameterComp. This change is mostly invisible to the user with a single backwards compatibility issue noted below.

Related Issues

Backwards incompatibilities

t_initial and t_duration are now inputs to the phase and cannot be connected to other targets (other than via promotion.)
Their values are available as outputs through t_initial_val and t_duration_val.

New Dependencies

  • Minimum OpenMDAO version is now 3.26.0
