-
From the Boundaries section of the action bar, click Stagnation Inlet
.
- Optional:
Customize the default
Name of the inlet.
-
Select the surface where fluid enters the domain.
-
Specify the magnitude and direction of the flow through the inlet. The
following options are available for specifying direction:
Option | Description |
---|
Normal |
Flow direction is normal to the opening. |
Specified |
Flow direction follows a custom vector that you specify. You can
choose a direction in the global axis system, a local axis system, or an
axis system that you specify in the app. |
-
Specify the
Temperature of the fluid flowing into the
inlet.
You can use a single uniform value, spatially-varying mapped data, or a JavaScript user subroutines that defines
the value programmatically.
In addition, you can apply a scale factor or amplitude to the value. Click , then
specify either or both of the following:
Option | Description |
---|
Scale factor |
A multiplier that is applied to the magnitude of the value in the
step. |
Amplitude |
Name of the amplitude curve that defines the magnitude of the value
during the step. |
-
Choose a Turbulence specification and customize its
settings to define the turbulent flow at the inlet. The following turbulence
specifications are available:
Option | Description |
---|
Viscosity ratio |
Define turbulence by specifying the eddy viscosity ratio. |
Intensity - Length scale |
Define turbulence by specifying the turbulence intensity,
characteristic length scale, and velocity scale. |
Turbulent viscosity |
Define turbulence by specifying the kinematic eddy
viscosity. |
The specific turbulence customization settings that appear depend on your
choice and on the turbulence model you chose in the physics definition. For a
full description of all available turbulence settings, see Initial Turbulence Options.
-
For compressible flow simulations, specify the Supersonic static
gauge pressure of the fluid at the inlet. The solver applies
this pressure value locally if the flow becomes supersonic.
-
For multispecies flow analyses, you can also specify the mass fraction of the
materials flowing through the inlet. For more information, see Defining Mass Fractions at an Inlet.
-
For a multiphase simulation using the Volume of Fluid (VOF) method, you can
also specify the material distribution flowing through the inlet. In addition,
gravity waves can be specified as part of the material distribution. For more
information, see Defining Volume Fractions at an Inlet
-
If surface-to-surface radiation is active, you can specify the radiation
behavior at the inlet. For more information, see Defining Surface-to-Surface Radiation Behavior at an Inlet.
-
If particle physics are active, you can specify how the particles interact with
the inlet. For more information, see Defining a Particle Boundary.
