Boundaries Section

Boundaries define flow and thermal conditions at the boundaries of the fluid domain. The primary flow boundary conditions are used to specify pressure or velocity.

Flow conditions are step-dependent actions.

Wall
Specifies fluid motion and heat transfer at a fluid-structure interface.
Velocity Inlet
Specifies the velocity of fluid passing through an opening.
See Defining a Velocity Inlet.
Volume Flow Rate
Specifies the volume flow rate of fluid passing through an opening.
See Defining a Volume Flow Rate Inlet.
Stagnation Inlet
Defines a flow inlet where stagnation pressure is specified.
See Defining a Stagnation Inlet.
Free Stream
Specifies far field boundary condition.
See Defining a Free Stream Boundary Condition.
Mass Flow Inlet
Specifies a mass flow inlet boundary.
See Defining a Mass Flow Inlet.
Pressure Outlet
Specifies the pressure at an opening where fluid flows out of the fluid domain.
See Defining a Pressure Outlet.
Mass Flow Split Outlet
Specifies a mass flow split outlet with a user specified split weight factor.
See Defining a Mass Flow Split Outlet.
Symmetry
Defines a symmetry boundary.
See Defining Symmetry.
Hydrostatic Pressure
Defines the value of pressure at a point in the fluid.
See Defining a Hydrostatic Pressure.
Mesh Motion
Defines a moving boundary.
See Defining Mesh Motion.
Human
Specifies a human model for which human comfort parameters are computed.
See Defining Human Boundary Conditions.
Human
Creates a human group, representing humans with a common set of human comfort parameters.
See Defining Human Groups.
