Convection
Use the Convection PropertyManager to apply convection boundary condition to selected faces of the model in thermal studies (steady state and transient). You can associate a
temperature curve
with the convection coefficient to simulate a temperature-dependent variation. In transient thermal studies, you can also associate a
time curve
to simulate time-dependency of the convection coefficient and the bulk temperature as well.
To define a convection boundary condition:
-
In the Simulation study tree, right-click Thermal Loads
and select Convection
.
-or-
Click Thermal Loads, Convection (Simulation toolbar).
-or-
Click Simulation, Loads/Fixture, Convection.
The Convection PropertyManager appears.
-
In the graphics area, select the faces for which the convection boundary condition is to be defined.
The selected faces appear in the Faces for Convection box .
To select all faces exposed to outside at once, click Select all exposed faces. To delete a face later, right-click the face and select Delete. See Selecting All Exposed Faces for details.
-
Select the unit system you want to use to enter the values of the Convection Coefficient and the Bulk Temperature.
-
Under Convection Coefficient, do the following:
-
Type a value for the Convection Coefficient .
-
Click Use Time Curve and then click Edit define or import a time curve and associate the convection coefficient with it.
-
Click Use Temperature Curve and then click Edit to define or import a temperature curve and associate the convection coefficient with it.
-
Under Bulk Ambient Temperature, do the following:
-
Type a value for the Bulk Ambient Temperature .
-
Click Use Time Curve and then click Edit to associate the bulk temperature with a time curve.
