- variableThe variable this initial condition is supposed to provide values for.
C++ Type:VariableName
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
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

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 boundary condition applies
C++ Type:std::vector<BoundaryName>
Controllable:No
Description:The list of boundaries (ids or names) from the mesh where this boundary condition applies
- 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
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.
- y_value0The y value to be set in IC
