SIMPLENonlinearAssembly

Solves the Navier-Stokes equations using the SIMPLENonlinearAssembly algorithm.

Overview

For the overview of the SIMPLE algorithm, please visit SIMPLE.

This executioner implements the same iteration but it uses MOOSE's native residual and Jacobian computing routines to build system matrices and right hand sides. Even though this introduces an overhead in terms of computational speed, it allows the utilization of the same variables, kernels and boundary conditions that are used in the monolithic solvers.

Example Input Syntax

The setup of a problem with the segregated solver in MOOSE is slightly different compared to conventional monolithic solvers. In this section, we highlight the main differences. For setting up a 2D simulation with the SIMPLE algorithm, we add three systems in MOOSE: one for each momentum component and another for the pressure. The different systems can be created within the Problem block:

[Problem]
  nl_sys_names = 'u_system v_system pressure_system'
  previous_nl_solution_required = true
[]
(contrib/moose/modules/navier_stokes/test/tests/finite_volume/ins/channel-flow/segregated/2d/2d-segregated-velocity.i)

It is visible that we requested that MOOSE keeps previous solution iterates as well. This is necessary to facilitate the relaxation processes mentioned in SIMPLE.

[Variables]
  [u]
    type = INSFVVelocityVariable
    initial_condition = 0.5
    solver_sys = u_system
    two_term_boundary_expansion = false
  []
  [v]
    type = INSFVVelocityVariable
    initial_condition = 0.0
    solver_sys = v_system
    two_term_boundary_expansion = false
  []
  [pressure]
    type = INSFVPressureVariable
    solver_sys = pressure_system
    initial_condition = 0.2
    two_term_boundary_expansion = false
  []
[]
(contrib/moose/modules/navier_stokes/test/tests/finite_volume/ins/channel-flow/segregated/2d/2d-segregated-velocity.i)

The kernels are then created similarly to the monolithic system, with the exception that now the kernels acting on pressure are slightly different:

[FVKernels]
  [p_diffusion]
    type = FVAnisotropicDiffusion
    variable = pressure
    coeff = "Ainv"
    coeff_interp_method = 'average'
  []

  [p_source]
    type = FVDivergence
    variable = pressure
    vector_field = "HbyA"
    force_boundary_execution = true
  []
[]
(contrib/moose/modules/navier_stokes/test/tests/finite_volume/ins/channel-flow/segregated/2d/2d-segregated-velocity.i)

By default, the coupling fields corresponding to A1HA^{-1}H and A1A^{-1} are called HbyA and Ainv, respectively. These fields are generated by INSFVRhieChowInterpolatorSegregated under the hood. This means that we need to add the user object responsible for generating these fields:

[UserObjects]
  [rc]
    type = INSFVRhieChowInterpolatorSegregated
    u = u
    v = v
    pressure = pressure
  []
[]
(contrib/moose/modules/navier_stokes/test/tests/finite_volume/ins/channel-flow/segregated/2d/2d-segregated-velocity.i)

Next, we add the SIMPLENonlinearAssembly executioner:

[Executioner]
  type = SIMPLENonlinearAssembly
  momentum_l_abs_tol = 1e-14
  pressure_l_abs_tol = 1e-14
  momentum_l_tol = 0
  pressure_l_tol = 0
  rhie_chow_user_object = 'rc'
  momentum_systems = 'u_system v_system'
  pressure_system = 'pressure_system'
  pressure_gradient_tag = ${pressure_tag}
  momentum_equation_relaxation = 0.8
  pressure_variable_relaxation = 0.3
  num_iterations = 150
  pressure_absolute_tolerance = 1e-13
  momentum_absolute_tolerance = 1e-13
  print_fields = false
[]
(contrib/moose/modules/navier_stokes/test/tests/finite_volume/ins/channel-flow/segregated/2d/2d-segregated-velocity.i)

We see that it has a parameter called "pressure_gradient_tag". This tag needs to be added to the pressure gradient kernels to enable the separation of terms needed in A1HA^{-1}H. This can be easily done as follows in the FVKernels:

[FVKernels]
  [u_pressure]
    type = INSFVMomentumPressure
    variable = u
    momentum_component = 'x'
    pressure = pressure
    extra_vector_tags = ${pressure_tag}
  []

  [v_pressure]
    type = INSFVMomentumPressure
    variable = v
    momentum_component = 'y'
    pressure = pressure
    extra_vector_tags = ${pressure_tag}
  []
[]
(contrib/moose/modules/navier_stokes/test/tests/finite_volume/ins/channel-flow/segregated/2d/2d-segregated-velocity.i)
