Icepak.assign_mass_flow_free_opening(assignment, boundary_name=None, temperature='AmbientTemp', radiation_temperature='AmbientRadTemp', pressure='AmbientPressure', mass_flow_rate='0kg_per_s', inflow=True, direction_vector=None)[source]#

Assign free opening boundary condition.

Parameters:

assignmentint or str or list: Integer indicating a face ID or a string indicating an object name. A list of face IDs or object names is also accepted.
boundary_namestr, optional: Boundary name. The default is None, in which case the name is generated automatically.
temperaturestr or float or dict or BoundaryDictionary, optional: Prescribed temperature at the boundary. If a string is set, a variable name or a number with the unit is expected. If a float is set, the unit 'cel' is automatically added. Assign a transient condition using the result of a function with the create_*_transient_assignment pattern.
radiation_temperaturestr or floaty, optional: Prescribed radiation temperature at the boundary. If a string is set, a variable name or a number with the unit is expected. If a float is set, the unit 'cel' is automatically added. Default is "AmbientRadTemp".
pressurefloat or str or dict or BoundaryDictionary, optional: Prescribed pressure (static or total coherently with flow type) at the boundary. If a string is set, a variable name or a number with the unit is expected. If a float is set, the unit 'pascal' is automatically added. Assign a transient condition using the result of a function with the create_*_transient_assignment pattern. The default is "AmbientPressure".
mass_flow_ratefloat or str or dict or BoundaryDictionary, optional: Prescribed pressure (static or total coherently with flow type) at the boundary. If a string is set, a variable name or a number with the unit is expected. If a float is set, the unit 'kg_per_s' is automatically added. Assign a transient condition using the result of a function with the create_*_transient_assignment pattern. The default is "0kg_per_s".
inflowbool, optional: Prescribe if the imposed mass flow is an inflow or an outflow. Default is "True", in which case an inflow is prescribed.
direction_vectorlist, optional: Prescribe the direction of the massflow. Default is "None", in which case a massflow normal to the boundary is prescribed.

Returns:

pyaedt.modules.Boundary.BoundaryObject: Boundary object when successful or None when failed.
