To Select Output Options for a Steady Thermal Analysis
To begin with you must have opened the dialog box for creating a
steady state thermal analysis.
1. Click the Output tab on the analysis dialog box.
2. If you do not want to calculate
Heat Flux, clear the check box.
Heat Flux is selected by default.

|
 If you are creating a linear steady-state thermal analysis without load histories, skip the remaining steps. |
4. If you have selected the
Nonlinear / Use Load Histories check box, select an option to specify the
Output Steps for which you want results—
Automatic Steps within Range or
User-defined Output Steps.
If you select User-defined Output Steps, different items appear on the tab. Skip to steps 7 through 10.
5. If you have selected
Automatic Steps within Range, specify a minimum time for the lower end of the
time range to report results for your analysis.
6. Specify a maximum time for the upper end of the time range or select Automatic.

|
If you have selected Automatic Steps within Range, skip the remaining steps.
|
7. Type a value for Number of Master Steps.
The table displays numbered rows representing the number of steps you selected.
8. Use the default values for each step to specify the spacing between steps or click
User-defined Steps to specify values.
When you click
User-defined Steps the maximum time step has the maximum value of time as defined in the table function for time dependence for a
constraint or
load set selected for the analysis.
If you have clicked the User-defined Steps button, you can click the Space Equally button to evenly space the steps.

Even if you specify load histories for a steady state thermal analysis, the loads are assumed to be applied slowly relative to the time it takes the temperature in the model to reach equilibrium. Thus, the steps only define the order of loading, and true transient effects are neglected.

9. Select the Full results check boxes to specify the steps at which to save full temperature and flux results.
10. Select the Temp load check boxes to specify the steps at which to save temperature load data to import a thermal load or a temperature field into Structure.
You can click
to save full results and temperature load data at all steps. You can click
to clear the check boxes for all steps.
