- variableThe variable this initial condition is supposed to provide values for.
C++ Type:VariableName
Description:The variable this initial condition is supposed to provide values for.
- x_valueThe x value to be set in IC
C++ Type:double
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.
