NSCoupled.NS_assemble(**NS_namespace)

NSCoupled.NS_solve(**NS_namespace)

NSCoupled.get_solvers(**NS_namespace)

and possibly: - scalars

NSCoupled.print_velocity_pressure_info(iter, error, **NS_namespace)

NSCoupled.scalar_assemble(**NS_namespace)

Assemble scalar equation.

NSCoupled.scalar_solve(**NS_namespace)

Solve scalar equation.

NSCoupled.setup(**NS_namespace)

Set up all equations to be solved.

NSfracStep.py

NSfracStep.assemble_first_inner_iter(**NS_namespace)

Called first thing on a new velocity/pressure iteration.

NSfracStep.get_solvers(**NS_namespace)

Return 4 linear solvers.

We are solving for

• tentative velocity

• pressure correction

• velocity update (unless lumping is switched on)

and possibly: - scalars

Assemble rhs of pressure equation.

NSfracStep.pressure_solve(**NS_namespace)

Solve pressure equation.

NSfracStep.print_velocity_pressure_info(num_iter, print_velocity_pressure_convergence, norm, info_blue, inner_iter, udiff, dp_, **NS_namespace)

NSfracStep.scalar_assemble(**NS_namespace)

Assemble scalar equation.

NSfracStep.scalar_solve(**NS_namespace)
