Description

When using a restart file, the initial guess of the state history is loaded from the given case. If any of the states are set to fix_final=True, the desired final state will be overridden during the restart file load.

For now, we should raise an error the user uses restart with fix_final=True on any state or control in the phase.
The error should instruct the user to use add_boundary_constraint on the state or control instead of a fix_final=True.

Example

TBD

Environment
