Specifies conditions on Mass and Momentum at a boundary.

Attributes

Attribute	Summary
option	The ‘Mass And Momentum’ option.
relative_pressure	‘Relative Pressure’ parameter.
relative_static_pressure	‘Relative Static Pressure’ parameter.
relative_total_pressure	‘Relative Total Pressure’ parameter.
u	‘U’ parameter.
v	‘V’ parameter.
w	‘W’ parameter.
velocity_axial_component	‘Velocity Axial Component’ parameter.
velocity_r_component	‘Velocity r Component’ parameter.
velocity_theta_component	‘Velocity Theta Component’ parameter.
normal_speed	‘Normal Speed’ parameter.
mass_flow_rate	‘Mass Flow Rate’ parameter.
corrected_mass_flow_rate	‘Corrected Mass Flow Rate’ parameter.
mass_flow_rate_area	‘Mass Flow Rate Area’ parameter.
reference_temperature	‘Reference Temperature’ parameter.
reference_pressure	‘Reference Pressure’ parameter.
relative_pressure_in_gas	‘Relative Pressure in Gas’ parameter.
pressure_profile_blend	Factor to blend between the specified pressure profile and a floating (implicit) pressure profile blend factor. 0.0 is fully implicit and 1.0 imposes the specified profile.
wall_velocity_relative_to	Sets whether wall velocities are evaluated relative to the specified boundary frame or the mesh motion. This is only used for moving mesh cases.
input_variable	‘Input Variable’ parameter.
implicit_pressure_averaging	Indicates whether pressure averaging is implicit.
weighting_option	Specifies the weighting option for average pressure outlets.
include_normal_viscous_force	Indicates whether normal viscous force is included at slip walls.
slip_model	Specifies a wall slip model.
shear_stress	Specifies the shear force at a wall.
axis_definition	Defines the axis for a cylindrical coordinate system or variables defined using cylindrical components.
wall_velocity	Specifies the velocity of a no-slip wall.
turbulent_wall_functions	Sets the turbulent near-wall treatment at a boundary.
mass_flow_update	Determines how the solver enforces the mass flow rate specified on an outflow boundary condition. Shift pressure updates the average pressure level on the boundary to give the required mass flow rate, Scale Mass Flows multiplies the solver computed mass flows by a factor to give the set value, and Constant Flux distributes the set value by area weighting over the boundary patch.
acoustic_reflectivity	Specifies acoustic reflection attributes of a boundary condition.
pressure_option	Specifies the pressure choice at an entrainment opening.
pressure_profile	Specifies pressure profile information for outlet BCs.

Parent	Summary
boundary_conditions	Specifies boundary conditions for all equations being solved.
