Extrude Command In Siemens NX(Illustrated Expression)
Body temperature is a very important boundary condition in finite element analysis(FEA). Defining body temperature correct way according to the engineering or physical problem is very important to obtain correct results. In this article of Mechanical Base, we will show you how to define body temperatures in ANSYS® Mechanical that changes with time. You can define a body temperature value as a body that changes with time which means it has different temperature values in changing time.

To define body temperature value to a body that changes with time in ANSYS® Mechanical, right-click on analysis system as shown by the green arrow above(Static Structural in this example) then hover over your mouse Insert tab as shown in the red box above. Click on Thermal Condition from the menu that opened as shown by the red arrow.
Select the geometry that you will define your thermal condition that changes with time as shown by the green arrow above. You can choose only bodies in this time-dependent boundary condition. After selecting the body, click on the Apply button in the Geometry section of Thermal Condition in ANSYS® Mechanical, as shown by the red arrow above.
To define the temperature value that changes with time in ANSYS® Mechanical, click on the little pop-up menu opener as shown by the red arrow above then click on the Tabular method from this pop-up menu.
You can add time values to your tabular data as shown by the red arrow. For example, enter a time value then press Enter from the keyboard. You can enter the temperature value next to this value in Tabular Data as in the red box.
As you can see above graph, the temperature value that changes with time is assigned. This situation for the body in analysis will be considered in solution process.
This is very easy like that to define temperature values that change with time to bodies in ANSYS® Mechanical.
