Command Qualifier
Some commands require a qualifier. The qualifier is used to distinguish one use of the command from another.
MATERIAL_MODEL( "air" ) {
density_model = "air at standard atmosphere"
viscosity_model = "air"
}
MATERIAL_MODEL( "aluminum" ) {
density_model = "aluminum"
conductivity_model = "aluminum"
}
ELEMENT_SET( "channel" ) {
material_model = "air"
}
NODAL_INITIAL_CONDITION( velocity ) {
default_values = { 1, 0, 0 }
}
NODAL_INITIAL_CONDITION( pressure ) {
default_value = 0
}
In the first command, the initial conditions are applied to velocity and in the second command they are applied to pressure. NODAL_INITIAL_CONDITION is currently the only command that uses the enumerated type of qualifier.
