BoundingBoxIC
BoundingBoxIC allows setting the initial condition of a value inside and outside of a specified box. The box is aligned with the x, y, z axes and is specified by passing in the x, y, z coordinates of the bottom left point and the top right point. Each of the coordinates of the "bottom_left" point MUST be less than those coordinates in the "top_right" point.
When setting the initial condition, if bottom_left <= Point <= top_right then the "inside" value is used. Otherwise the "outside" value is used.
commentnote
When using this IC, only a single bounding box my be specified within the domain. If multiple bounding boxes are needed, this capability is implemented in the phase_field module as MultiBoundingBoxIC.
Class Description
BoundingBoxIC allows setting the initial condition of a value inside and outside of a specified box. The box is aligned with the x, y, z axes
Input Parameters
- blockThe list of blocks (ids or names) that this object will be applied
C++ Type:std::vector<SubdomainName>
Controllable:No
Description:The list of blocks (ids or names) that this object will be applied
- boundaryThe list of boundaries (ids or names) from the mesh where this object applies
C++ Type:std::vector<BoundaryName>
Controllable:No
Description:The list of boundaries (ids or names) from the mesh where this object applies
- inside0The value of the variable inside the box
Default:0
C++ Type:double
Unit:(no unit assumed)
Controllable:No
Description:The value of the variable inside the box
- int_width0The width of the diffuse interface. Set to 0 for sharp interface.
Default:0
C++ Type:double
Unit:(no unit assumed)
Controllable:No
Description:The width of the diffuse interface. Set to 0 for sharp interface.
- outside0The value of the variable outside the box
Default:0
C++ Type:double
Unit:(no unit assumed)
Controllable:No
Description:The value of the variable outside the box
- stateCURRENTThis parameter is used to set old state solutions at the start of simulation. If specifying multiple states at the start of simulation, use one IC object for each state being specified. The states are CURRENT=0 OLD=1 OLDER=2. States older than 2 are not currently supported. When the user only specifies current state, the solution is copied to the old and older states, as expected. This functionality is mainly used for dynamic simulations with explicit time integration schemes, where old solution states are used in the velocity and acceleration approximations.
Default:CURRENT
C++ Type:MooseEnum
Options:CURRENT, OLD, OLDER
Controllable:No
Description:This parameter is used to set old state solutions at the start of simulation. If specifying multiple states at the start of simulation, use one IC object for each state being specified. The states are CURRENT=0 OLD=1 OLDER=2. States older than 2 are not currently supported. When the user only specifies current state, the solution is copied to the old and older states, as expected. This functionality is mainly used for dynamic simulations with explicit time integration schemes, where old solution states are used in the velocity and acceleration approximations.
- z10The z coordinate of the lower left-hand corner of the box
Default:0
C++ Type:double
Unit:(no unit assumed)
Controllable:No
Description:The z coordinate of the lower left-hand corner of the box
- z20The z coordinate of the upper right-hand corner of the box
Default:0
C++ Type:double
Unit:(no unit assumed)
Controllable:No

Optional Parameters
- control_tagsAdds user-defined labels for accessing object parameters via control logic.
C++ Type:std::vector<std::string>
Controllable:No
Description:Adds user-defined labels for accessing object parameters via control logic.
- enableTrueSet the enabled status of the MooseObject.
Default:True
C++ Type:bool
Controllable:No
Description:Set the enabled status of the MooseObject.
- ignore_uo_dependencyFalseWhen set to true, a UserObject retrieved by this IC will not be executed before the this IC
Default:False
C++ Type:bool
Controllable:No
Description:When set to true, a UserObject retrieved by this IC will not be executed before the this IC
Advanced Parameters
- prop_getter_suffixAn optional suffix parameter that can be appended to any attempt to retrieve/get material properties. The suffix will be prepended with a '_' character.
C++ Type:MaterialPropertyName
Unit:(no unit assumed)
Controllable:No
Description:An optional suffix parameter that can be appended to any attempt to retrieve/get material properties. The suffix will be prepended with a '_' character.
- use_interpolated_stateFalseFor the old and older state use projected material properties interpolated at the quadrature points. To set up projection use the ProjectedStatefulMaterialStorageAction.
Default:False
C++ Type:bool
Controllable:No
Description:For the old and older state use projected material properties interpolated at the quadrature points. To set up projection use the ProjectedStatefulMaterialStorageAction.

# Example of reactive transport model with precipitation and dissolution.
# Calcium (ca2) and bicarbonate (hco3) reaction to form calcite (CaCO3).
# Models bicarbonate injection following calcium injection, so that a
# moving reaction front forms a calcite precipitation zone. As the front moves,
# the upstream side of the front continues to form calcite via precipitation,
# while at the downstream side, dissolution of the solid calcite occurs.
#
# The reaction network considered is as follows:
# Aqueous equilibrium reactions:
# a) h+ + hco3- = CO2(aq), Keq = 10^(6.341)
# b) hco3- = h+ + CO23-, Keq = 10^(-10.325)
# c) ca2+ + hco3- = h+ + CaCO3(aq), Keq = 10^(-7.009)
# d) ca2+ + hco3- = cahco3+, Keq = 10^(-0.653)
# e) ca2+ = h+ + CaOh+, Keq = 10^(-12.85)
# f) - h+ = oh-, Keq = 10^(-13.991)
#
# Kinetic reactions
# g) ca2+ + hco3- = h+ + CaCO3(s), A = 0.461 m^2/L, k = 6.456542e-2 mol/m^2 s,
# Keq = 10^(1.8487)
#
# The primary chemical species are h+, hco3- and ca2+. The pressure gradient is fixed,
# and a conservative tracer is also included.
#
# This example is taken from:
# Guo et al, A parallel, fully coupled, fully implicit solution to reactive
# transport in porous media using the preconditioned Jacobian-Free Newton-Krylov
# Method, Advances in Water Resources, 53, 101-108 (2013).

# 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.
#
# Note: this model is computationally expensive, so should be run with multiple cores,
# preferably on a cluster.
