Description:The default timestep size between solves
IterationAdaptiveDT
Adjust the timestep based on the number of iterations
Description
The IterationAdaptiveDT Time Stepper provides a means to adapt the time step size based on the difficulty of the solution.
IterationAdaptiveDT grows or shrinks the time step based on the number of iterations taken to obtain a converged solution in the last converged step. The required optimal_iterations parameter controls the number of nonlinear iterations per time step that provides optimal solution efficiency. If more iterations than that are required to obtain a converged solution, the time step may be too large, resulting in undue solution difficulty, while if fewer iterations are required, it may be possible to take larger time steps to obtain a solution more quickly.
A second parameter, iteration_window, is used to control the size of the region in which the time step is held constant. As shown in Figure 1, if the number of nonlinear iterations for convergence is lower than (optimal_iterations-iteration_window), the time step is increased, while if more than (optimal_iterations+iteration_window), iterations are required, the time step is decreased. The iteration_window parameter is optional. If it is not specified, it defaults to 1/5 the value specified for optimal_iterations.
The decision on whether to grow or shrink the time step is based both on the number of nonlinear iterations and the number of linear iterations. The parameters mentioned above are used to control the optimal iterations and window for nonlinear iterations. The same criterion is applied to the linear iterations. Another parameter, linear_iteration ratio, which defaults to 25, is used to control the optimal iterations and window for the linear iterations. These are calculated by multiplying linear_iteration_ratio by optimal iterations and iteration window, respectively.
To grow the time step, the growth criterion must be met for both the linear iterations and nonlinear iterations. If the time step shrinkage criterion is reached for either the linear or nonlinear iterations, the time step is decreased. To control the time step size only based on the number of nonlinear iterations, set linear_iteration_ratio to a large number.
If the time step is to be increased or decreased, that is done using the factors specified with the growth_factor and cutback_factor, respectively. If a solution fails to converge when adaptive time stepping is active, a new attempt is made using a smaller time step in the same manner as with the fixed time step methods. The maximum and minimum time steps can be optionally specified in the Executioner block using the dtmax and dtmin parameters, respectively.
In addition to controlling the time step based on the iteration count, IterationAdaptiveDT also has an option to limit the time step based on the behavior of a time-dependent function, optionall specified by providing the function name in timestep_limiting_function. This is typically a function that is used to drive boundary conditions of the model. The step is cut back if the change in the function from the previous step exceeds the value specified in max_function_change. This allows the step size to be changed to limit the change in the boundary conditions applied to the model over a step. In addition to that limit, the boolean parameter force_step_every_function_point can be set to true to force a time step at every point in a PiecewiseLinear function.

# Using the results from the equilibrium run to provide the initial condition for
# porepressure, we now inject a gas phase into the brine-saturated reservoir. In this
# example, where the mesh used is identical to the mesh used in gravityeq.i, we can use
# the basic restart capability by simply setting the initial condition for porepressure
# using the results from gravityeq.i.
#
# Even though the gravity equilibrium is established using a 2D mesh, in this example,
# we shift the mesh 0.1 m to the right and rotate it about the Y axis to make a 2D radial
# model.
#
# Methane injection takes place over the surface of the hole created by rotating the mesh,
# and hence the injection area is 2 pi r h. We can calculate this using an AreaPostprocessor,
# and then use this in a ParsedFunction to calculate the injection rate so that 10 kg/s of
# methane is injected.
#
# Results can be improved by uniformly refining the initial mesh.
#
# Note: as this example uses the results from a previous simulation, gravityeq.i MUST be
# run before running this input file.

# Considers the mechanics solution for a thick spherical shell that is uniformly
# pressurized on the inner and outer surfaces, using 2D axisymmetric geometry.
# This test uses the strain calculators ComputeAxisymmetricRZSmallStrain
# and ComputeAxisymmetricRZIncrementalStrain which are generated by the
# TensorMechanics MasterAction depending on the cli_args given in the tests file.
#
# From Roark (Formulas for Stress and Strain, McGraw-Hill, 1975), the radially-dependent
# circumferential stress in a uniformly pressurized thick spherical shell is given by:
#
# S(r) = [ Pi[ri^3(2r^3+ro^3)] - Po[ro^3(2r^3+ri^3)] ] / [2r^3(ro^3-ri^3)]
#
# where:
# Pi = inner pressure
# Po = outer pressure
# ri = inner radius
# ro = outer radius
#
# The tests assume an inner and outer radii of 5 and 10, with internal and external
# pressures of 100000 and 200000, respectively. The resulting compressive tangential
# stress is largest at the inner wall and, from the above equation, has a value
# of -271429.

# Using the results from the equilibrium run to provide the initial condition for
# porepressure, we now inject a gas phase into the brine-saturated reservoir. In this
# example, the mesh is not identical to the mesh used in gravityeq.i. Rather, it is
# generated so that it is more refined near the injection boundary and at the top of
# the model, as that is where the gas plume will be present.
#
# To use the hydrostatic pressure calculated using the gravity equilibrium run as the initial
# condition for the pressure, a SolutionUserObject is used, along with a SolutionFunction to
# interpolate the pressure from the gravity equilibrium run to the initial condition for liqiud
# porepressure in this example.
#
# Even though the gravity equilibrium is established using a 2D mesh, in this example,
# we use a mesh shifted 0.1 m to the right and rotate it about the Y axis to make a 2D radial
# model.
#
# Methane injection takes place over the surface of the hole created by rotating the mesh,
# and hence the injection area is 2 pi r h. We can calculate this using an AreaPostprocessor,
# and then use this in a ParsedFunction to calculate the injection rate so that 10 kg/s of
# methane is injected.
#
# Note: as this example uses the results from a previous simulation, gravityeq.i MUST be
# run before running this input file.

# Two phase density-driven convection of dissolved CO2 in brine
#
# The model starts with CO2 in the liquid phase only. The CO2 diffuses into the brine.
# As the density of the CO2-saturated brine is greater
# than the unsaturated brine, a gravitational instability arises and density-driven
# convection of CO2-rich fingers descend into the unsaturated brine.
#
# The instability is seeded by a random perturbation to the porosity field.
# Mesh adaptivity is used to refine the mesh as the fingers form.

# Considers the mechanics solution for a thick spherical shell that is uniformly
# pressurized on the inner and outer surfaces. Three versions of the test are
# provided, assuming 1D spherical geometry (1D-SPH), 2D axisymmetic geometry
# (2D-RZ), and 3D geometry (3D). The tests demonstrate that all three geometric
# approaches produce the same correct solution.
#
# From Roark (Formulas for Stress and Strain, McGraw-Hill, 1975), the radially-dependent
# circumferential stress in a uniformly pressurized thick spherical shell is given by:
#
# S(r) = [ Pi[ri^3(2r^3+ro^3)] - Po[ro^3(2r^3+ri^3)] ] / [2r^3(ro^3-ri^3)]
#
# where:
# Pi = inner pressure
# Po = outer pressure
# ri = inner radius
# ro = outer radius
#
# The tests assume an inner and outer radii of 5 and 10, with internal and external
# pressures of 100000 and 200000, respectively. The resulting compressive tangential
# stress is largest at the inner wall and, from the above equation, has a value
# of -271429.
#
# RESULTS are below. Since stresses are average element values, values for the
# edge element and one-element-in are used to extrapolate the stress to the
# inner surface. The vesrion of the tests that are checked use the coarsest meshes.

# This is a basic test of the system for continuum damage mechanics
# materials. It uses ScalarMaterialDamage for the damage model,
# which simply gets its damage index from another material. In this
# case, we prescribe the evolution of the damage index using a
# function. A single element has a fixed prescribed displacement
# on one side that puts the element in tension, and then the
# damage index evolves from 0 to 1 over time, and this verifies
# that the stress correspondingly drops to 0.

# Considers the mechanics solution for a thick spherical shell that is uniformly
# pressurized on the inner and outer surfaces. Three versions of the test are
# provided, assuming 1D spherical geometry (1D-SPH), 2D axisymmetic geometry
# (2D-RZ), and 3D geometry (3D). The tests demonstrate that all three geometric
# approaches produce the same correct solution.
#
# From Roark (Formulas for Stress and Strain, McGraw-Hill, 1975), the radially-dependent
# circumferential stress in a uniformly pressurized thick spherical shell is given by:
#
# S(r) = [ Pi[ri^3(2r^3+ro^3)] - Po[ro^3(2r^3+ri^3)] ] / [2r^3(ro^3-ri^3)]
#
# where:
# Pi = inner pressure
# Po = outer pressure
# ri = inner radius
# ro = outer radius
#
# The tests assume an inner and outer radii of 5 and 10, with internal and external
# pressures of 100000 and 200000, respectively. The resulting compressive tangential
# stress is largest at the inner wall and, from the above equation, has a value
# of -271429.
#
# RESULTS are below. Since stresses are average element values, values for the
# edge element and one-element-in are used to extrapolate the stress to the
# inner surface. The vesrion of the tests that are checked use the coarsest meshes.
#

# Considers the mechanics solution for a thick spherical shell that is uniformly
# pressurized on the inner and outer surfaces. Three versions of the test are
# provided, assuming 1D spherical geometry (1D-SPH), 2D axisymmetic geometry
# (2D-RZ), and 3D geometry (3D). The tests demonstrate that all three geometric
# approaches produce the same correct solution.
#
# From Roark (Formulas for Stress and Strain, McGraw-Hill, 1975), the radially-dependent
# circumferential stress in a uniformly pressurized thick spherical shell is given by:
#
# S(r) = [ Pi[ri^3(2r^3+ro^3)] - Po[ro^3(2r^3+ri^3)] ] / [2r^3(ro^3-ri^3)]
#
# where:
# Pi = inner pressure
# Po = outer pressure
# ri = inner radius
# ro = outer radius
#
# The tests assume an inner and outer radii of 5 and 10, with internal and external
# pressures of 100000 and 200000, respectively. The resulting compressive tangential
# stress is largest at the inner wall and, from the above equation, has a value
# of -271429.
#
# RESULTS are below. Since stresses are average element values, values for the
# edge element and one-element-in are used to extrapolate the stress to the
# inner surface. The vesrion of the tests that are checked use the coarsest meshes.

modules/combined/test/tests/solid_mechanics/spherical_shell/1D-SPH_test.i
# Considers the mechanics solution for a thick spherical shell that is uniformly
# pressurized on the inner and outer surfaces. Three versions of the test are
# provided, assuming 1D spherical geometry (1D-SPH), 2D axisymmetic geometry
# (2D-RZ), and 3D geometry (3D). The tests demonstrate that all three geometric
# approaches produce the same correct solution.
#
# From Roark (Formulas for Stress and Strain, McGraw-Hill, 1975), the radially-dependent
# circumferential stress in a uniformly pressurized thick spherical shell is given by:
#
# S(r) = [ Pi[ri^3(2r^3+ro^3)] - Po[ro^3(2r^3+ri^3)] ] / [2r^3(ro^3-ri^3)]
#
# where:
# Pi = inner pressure
# Po = outer pressure
# ri = inner radius
# ro = outer radius
#
# The tests assume an inner and outer radii of 5 and 10, with internal and external
# pressures of 100000 and 200000, respectively. The resulting compressive tangential
# stress is largest at the inner wall and, from the above equation, has a value
# of -271429.
#
# RESULTS are below. Since stresses are average element values, values for the
# edge element and one-element-in are used to extrapolate the stress to the
# inner surface. The vesrion of the tests that are checked use the coarsest meshes.

# Example of reactive transport model with dissolution of dolomite
#
# The equilibrium system has 5 primary species (Variables) and
# 5 secondary species (PorousFlowMassFractionAqueousEquilibrium).
# Some of the equilibrium constants have been chosen rather arbitrarily.
#
# Equilibrium reactions
# H+ + HCO3- = CO2(aq)
# -H+ + HCO3- = CO32-
# HCO3- + Ca2+ = CaHCO3+
# HCO3- + Mg2+ = MgHCO3+
# HCO3- + Fe2+ = FeHCO3+
#
# The kinetic reaction that dissolves dolomite involves all 5 primary species.
#
# -2H+ + 2HCO3- + Ca2+ + 0.8Mg2+ + 0.2Fe2+ = CaMg0.8Fe0.2(CO3)2
#
# The initial concentration of precipitated dolomite is high, so it starts
# to dissolve immediately, increasing the concentrations of the primary species.
#
# Only single-phase, fully saturated physics is used.
# The pressure gradient is fixed, so that the Darcy velocity is 0.1m/s.
#
# Primary species are injected from the left side, and they flow to the right.
# Less dolomite dissolution therefore occurs on the left side (where
# the primary species have higher concentration).
#
# This test is more fully documented in tutorial_13

# Two phase density-driven convection of dissolved CO2 in brine
#
# Initially, the model has a gas phase at the top with a saturation of 0.29
# (which corresponds to an initial value of zi = 0.2).
# Diffusion of the dissolved CO2
# component from the saturated liquid to the unsaturated liquid below reduces the
# amount of CO2 in the gas phase. As the density of the CO2-saturated brine is greater
# than the unsaturated brine, a gravitational instability arises and density-driven
# convection of CO2-rich fingers descend into the unsaturated brine.
#
# The instability is seeded by a random perturbation to the porosity field.
# Mesh adaptivity is used to refine the mesh as the fingers form.

# Considers the mechanics solution for a thick spherical shell that is uniformly
# pressurized on the inner and outer surfaces. Three versions of the test are
# provided, assuming 1D spherical geometry (1D-SPH), 2D axisymmetic geometry
# (2D-RZ), and 3D geometry (3D). The tests demonstrate that all three geometric
# approaches produce the same correct solution.
#
# From Roark (Formulas for Stress and Strain, McGraw-Hill, 1975), the radially-dependent
# circumferential stress in a uniformly pressurized thick spherical shell is given by:
#
# S(r) = [ Pi[ri^3(2r^3+ro^3)] - Po[ro^3(2r^3+ri^3)] ] / [2r^3(ro^3-ri^3)]
#
# where:
# Pi = inner pressure
# Po = outer pressure
# ri = inner radius
# ro = outer radius
#
# The tests assume an inner and outer radii of 5 and 10, with internal and external
# pressures of 100000 and 200000, respectively. The resulting compressive tangential
# stress is largest at the inner wall and, from the above equation, has a value
# of -271429.
#
# RESULTS are below. Since stresses are average element values, values for the
# edge element and one-element-in are used to extrapolate the stress to the
# inner surface. The vesrion of the tests that are checked use the coarsest meshes.

# Considers the mechanics solution for a thick spherical shell that is uniformly
# pressurized on the inner and outer surfaces. Three versions of the test are
# provided, assuming 1D spherical geometry (1D-SPH), 2D axisymmetic geometry
# (2D-RZ), and 3D geometry (3D). The tests demonstrate that all three geometric
# approaches produce the same correct solution.
#
# From Roark (Formulas for Stress and Strain, McGraw-Hill, 1975), the radially-dependent
# circumferential stress in a uniformly pressurized thick spherical shell is given by:
#
# S(r) = [ Pi[ri^3(2r^3+ro^3)] - Po[ro^3(2r^3+ri^3)] ] / [2r^3(ro^3-ri^3)]
#
# where:
# Pi = inner pressure
# Po = outer pressure
# ri = inner radius
# ro = outer radius
#
# The tests assume an inner and outer radii of 5 and 10, with internal and external
# pressures of 100000 and 200000, respectively. The resulting compressive tangential
# stress is largest at the inner wall and, from the above equation, has a value
# of -271429.
#
# RESULTS are below. Since stresses are average element values, values for the
# edge element and one-element-in are used to extrapolate the stress to the
# inner surface. The vesrion of the tests that are checked use the coarsest meshes.

# Considers the mechanics solution for a thick spherical shell that is uniformly
# pressurized on the inner and outer surfaces, using 2D axisymmetric geometry.
# This test uses the strain calculators ComputeAxisymmetricRZSmallStrain
# and ComputeAxisymmetricRZIncrementalStrain which are generated by the
# TensorMechanics MasterAction depending on the cli_args given in the tests file.
#
# From Roark (Formulas for Stress and Strain, McGraw-Hill, 1975), the radially-dependent
# circumferential stress in a uniformly pressurized thick spherical shell is given by:
#
# S(r) = [ Pi[ri^3(2r^3+ro^3)] - Po[ro^3(2r^3+ri^3)] ] / [2r^3(ro^3-ri^3)]
#
# where:
# Pi = inner pressure
# Po = outer pressure
# ri = inner radius
# ro = outer radius
#
# The tests assume an inner and outer radii of 5 and 10, with internal and external
# pressures of 100000 and 200000, respectively. The resulting compressive tangential
# stress is largest at the inner wall and, from the above equation, has a value
# of -271429.
