-
Display the surface heat flux load editor using one of the following
methods:
-
Click the arrow to the right of the Distribution
field, and select the option of your choice from the list that appears:
-
Select Uniform to define a load that is
uniform over the surface. For this option, the magnitude you provide must be
the flux per unit area.
-
Select User-defined to define the magnitude
of the load in user subroutine
DFLUX. (This option is valid only in
Abaqus/Standard
analyses.) See the following sections for more information:
-
Select Total Flux to define a load that is
uniform over the surface. For this option, the magnitude you provide must be
the total magnitude of the flux applied to the surface (instead of flux per
unit area).
-
Select an analytical field, labeled with an (A), or a discrete
field, labeled with a (D), to define a spatially varying surface heat flux.
Only analytical fields and discrete fields that are valid for this load type
are displayed in the selection list.
Alternatively, you can click
to create a new analytical field. (See
The Analytical Field toolset
for more information.)
-
If you selected the Uniform, Total
Flux, analytical field, or discrete field distribution option,
perform the following steps:
-
In the Magnitude text field, enter the
surface heat flux magnitude. A positive magnitude indicates heat flow into the
surface.
For a Uniform distribution, enter the total
flux magnitude divided by the surface area over which the flux is applied
(units JT−1L−2).
For a Total Flux distribution, enter the
total magnitude of the flux (units JT−1).
Abaqus/CAE
calculates a constant uniform surface flux from the flux magnitude entered.
-
If desired, click the arrow to the right of the
Amplitude field, and select the amplitude of your choice
from the list that appears. Alternatively, you can click
to create a new amplitude. (See
The Amplitude toolset
for more information.)
-
Click OK to save your data and to exit the
editor.
-
If you selected the User-defined distribution
option, perform the following steps:
-
If desired, enter the surface heat flux magnitude in the
Magnitude field (units
JT−1L−2). A positive magnitude indicates
heat flow into the surface.
Magnitude data that you enter in the editor are passed into the
user subroutine.
-
Click OK to save your data and to exit the
editor.
-
Enter the
Job module
and display the job editor for the analysis job of interest. (For more
information, see
Creating, editing, and manipulating jobs.)
-
In the job editor, click the General tab, and
specify the file containing the user subroutine that defines the load
magnitude. For more information, see
Specifying general job settings.
Note:
You can specify only one user subroutine file in the job editor;
if your analysis involves more than one user subroutine, you must combine the
user subroutines into one file and then specify that file.
