Detailed Description

Parameters for the incompressible flow stage arrangement.

Carries what varies between simulations. What does not vary, the stage ordering, is fixed by setup_flow: buoyancy must precede the projection or the solve removes the divergence it injects, the wall condition must follow every stage that writes velocity, and carried scalars must be advected by the projected velocity rather than the raw one. Those are correctness constraints, not preferences, and they are the part callers get wrong.
