Display the surface concentration 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.
-
Select User-defined to define the magnitude of the load in user subroutine DFLUX. See the following sections for more information:
-
Select an analytical field, labeled with an (A), or a discrete field, labeled with a (D), to define a spatially varying load. 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, analytical field, or discrete field distribution option, perform the following steps:
- In the Magnitude text field, enter the concentration flux density (units PLT−1). A positive magnitude indicates concentration flow into the surface.
- 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 concentration flux density in the Magnitude field (units PLT−1). A positive magnitude indicates concentration 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.
