You can create a temperature boundary condition to specify a temperature for the selected region.
To specify temperature in a region:
Display the temperature boundary condition editor using one of the following methods:
To create a new temperature boundary condition, follow the procedure outlined in “Creating boundary conditions,” Section 16.8.2 (Category: Other; Types for Selected Step: Temperature).
To edit an existing temperature boundary condition using menus or managers, see “Editing step-dependent objects,” Section 3.4.12. To edit the region to which the boundary condition is applied, see “Editing the region to which a prescribed condition is applied,” Section 16.8.4.
If a Method field appears toward the top of the editor, click the arrow to the right of the field, and select one of the following:
Select Specify magnitude if you want to specify a value for the temperature.
Select Fixed at current magnitude if you want to fix the temperature magnitude at its final value from the previous general step.
If a Distribution field appears in the editor, click the arrow to the right of the field, and select one of the following:
Select Uniform to define a uniform boundary condition.
Select User-defined to define the boundary condition in user subroutine DISP. See the following sections for more information:
If you are defining the boundary condition directly in the editor (and not in user subroutine DISP), perform the following steps:
If applicable, enter the temperature magnitude in the Magnitude field.
If applicable, 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 Create to create a new amplitude. (See Chapter 38, “The Amplitude toolset,” for more information.)
Note: The Magnitude and Amplitude fields are unavailable if you are creating the boundary condition in the initial step (in which case the magnitude is always zero) or are fixing the magnitude at its final value from the previous analysis step.
If you are defining the boundary condition in user subroutine DISP, perform the following steps:
If desired, enter the temperature magnitude in the Magnitude field. Magnitude data that you enter in the editor are passed into the user subroutine.
(The Magnitude field is unavailable if you are creating the boundary condition in the initial step.)
Click OK to save any entered 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,” Section 18.5.)
In the job editor, click the General tab, and specify the file containing the user subroutine that defines the boundary condition. For more information, see “Specifying general job settings,” Section 18.6.6.
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.
If a shell region is selected, enter the temperature degrees of freedom that you want to specify in the Degrees of freedom field. For information on how shell temperature degrees of freedom are labeled, see either “Heat transfer shell elements” or “Coupled temperature-displacement shell elements” in “Choosing a shell element,” Section 23.6.2 of the ABAQUS Analysis User's Manual.
You can enter multiple degrees of freedom, from 11 to 31, inclusive, by separating each number with a comma. For example, if you want to specify degrees of freedom 11, 12, and 13, you must enter the following:
11,12,13
Click OK to save your data and to exit the editor.
