ANSYS® provides very good tools for thermal conditions. Here, you can find the information about how to define temperatures in ANSYS® Mechanical bodies.
If you are inside these analyses; Steady-State Thermal, Transient-State Thermal, and Thermal-Electric in ANSYS® Mechanical, you -can define temperatures on bodies.
Inside the ANSYS® Mechanical, just right-click on the analyses which is ‘Steady-State Thermal’ above example. Inside ‘Insert’ click on ‘Temperature to define temperature on a body or part.
Select required geometries sections of your bodies or assemblies as shown by the green arrows above then click on the ‘Apply’ button as shown by the red arrow above.
Click on the little pop-up menu as shown by the red arrow above. You can define your temperature as ‘Constant’, ‘Tabular’ or ‘Function’.
The default selection is ‘Constant’ that you can directly enter the required value in the ‘Magnitude’ section.
If you select ‘Tabular’, you can enter your temperature value from the table below, by entering time and correspondingly changing temperature as tabular data. It is very useful if you want to enter your temperature value changing with the changing time in ANSYS® Mechanical.
In the ‘Function’ option, you need to define your temperature value as a function in which the variable is ‘time’.
As you see above we define the temperature as a function of ‘time’ shown in the red box above in ANSYS® Mechanical. You can see the temperature value which is changing with the changing time. You can also change the ‘Number Of Segments’ above as shown by the green arrow.
