Temperature Options for Transient Thermal Analysis
These items appear on the Temperatures tab on the Transient Thermal Analysis Definition dialog box:
Distribution—Specify initial temperature distribution—Uniform or MecT.
Temperature—Enter an initial temperature if you selected Uniform for Distribution. This temperature value must be the same as any prescribed temperatures in the constraint set.
These additional items appear on the tab only if you select MecT for Distribution:
Use temperatures from previous design study—You can select this check box option if you want to use temperature results from a previously run steady thermal analysis for the initial temperature in your transient thermal analysis. If this option is not selected, Creo Simulate runs the steady thermal analysis as part of running the transient thermal analysis.
Design Study—If you selected the option Use temperatures from previous design study, select a design study to include in the transient thermal analysis.
Thermal Analysis—Select a steady thermal analysis.
Load Set—Select a load set.
These options are available for all transient thermal analyses:
Accuracy—Enter a value for the acceptable fractional temperature error.
Estimated Variation—Enter a value for temperature variation or select Auto.
Automatically smooth convections—Select this option to turn on convection conditions gradually.
