Dirichlet Type Boundary Condition

Can anybody explain how the dirichlet type bc is used in SU2. I want to use it as a mass flow outlet in a inviscid problem.

Best,

If I were you I would focus on

%
% Inlet boundary type (TOTAL_CONDITIONS, MASS_FLOW, INPUT_FILE)
INLET_TYPE= TOTAL_CONDITIONS
%
% Inlet boundary marker(s) with the following formats (NONE = no marker)
% Total Conditions: (inlet marker, total temp, total pressure, flow_direction_x,
% flow_direction_y, flow_direction_z, ... ) where flow_direction is
% a unit vector.
% Mass Flow: (inlet marker, density, velocity magnitude, flow_direction_x,
% flow_direction_y, flow_direction_z, ... ) where flow_direction is
% a unit vector.
% Input File: (inlet marker, 0.0, 0.0, 0.0, 0.0, 0.0, ... ).
MARKER_INLET= ( NONE )

Best,
Francisco

PD.- Inlet in inviscid compressible fluids is a delicate math problem that require an approach based on characteristics.
