- variableThe variable this initial condition is supposed to provide values for.
C++ Type:VariableName
Unit:(no unit assumed)
Controllable:No
Description:The variable this initial condition is supposed to provide values for.
- x_valueThe x value to be set in IC
C++ Type:double
Unit:(no unit assumed)
Controllable:No
Description:The x value to be set in IC
VectorConstantIC
The VectorConstantIC class is used to set initial values of components of a vector variable. The x component can be set through the x_value parameter, the y component through y_value, and the z component through z_value. Note that x_value is required. If y_value or z_value are not supplied, they are defaulted to zero.
Sets constant component values for a vector field variable.
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
- 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.
- y_value0The y value to be set in IC
Default:0
C++ Type:double
Unit:(no unit assumed)
Controllable:No
Description:The y value to be set in IC
- z_value0The z value to be set in IC
Default:0
C++ Type:double
Unit:(no unit assumed)
Controllable:No
Description:The z value to be set in IC
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.
