-
From the Boundaries section of the action bar, click Volume Flow Rate
.
- Optional:
Customize the default
Name of the inlet.
-
Select the surface where fluid enters the domain.
-
Specify the
Volume Flow Rate of the fluid flowing into
this inlet in a specified time period.
If you want to apply a scale factor or amplitude to the flow rate values, click , then
specify either or both of the following:
Option | Description |
---|
Scale factor |
A multiplier that is applied to the magnitude of the flow rate
component in each step. |
Amplitude |
Name of the amplitude curve that defines the magnitude of the flow
rate during the step. |
-
Specify the
Temperature of the fluid flowing into this
inlet.
If you want to apply a scale factor or amplitude to the temperature values, click , then
specify either or both of the following:
Option | Description |
---|
Scale factor |
A multiplier that is applied to the magnitude of the flow rate in
each step. |
Amplitude |
Name of the amplitude curve that defines the magnitude of the flow
rate during the step. |

Describe the turbulent flow at this inlet by selecting a Turbulence
specification and customizing its settings. 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
specification 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 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 enabled in the fluid physics, 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.
