In this article of Mechanical Base, we will show how to define Force values that change with time in ANSYS® Mechanical. To define forces that change with time, you need to enter values of forces in Tabular Data. We will show you how to do it in ANSYS® Mechanical. You know that force is a boundary condition in the physical finite element analysis(FEA) systems. So defining force value that complies with the real physical system is very important to obtain correct results from the analysis.

Mechanical, you need to open the Mechanical interface. In this Mechanical interface, you need to right-click to your analysis system(in this example, it is Static Structural) as shown above. Then you need to hover your Mouse at Insert as shown, then click on the Force as shown by the blue box above in ANSYS® Mechanical.
Select your feature in your part such as selected as a face as in this example above as shown by the blue arrow. The geometry selection as done by the Geometry tab in force assignation that changes with time command as shown by the red arrow. When you select the face to apply force, click apply in the Geometry tab in ANSYS® Mechanical.
You can assign your Force to bodies as Components or Vectors that you can select from Define By section. In this example, we selected it as Components. Click on the little pop-up menu as shown by the red arrow above then click on the Tabular(Time) option as shown in the red box.
Do the same thing in the former step to assign a force that changes with time for each component as shown in the red box above.
You can adjust the time from Tabular Data and you can add a time row as shown by the red arrow above. Press the Enter button from your keyboard after creating a time step as shown by the red arrow above. Enter your whole force values for each component in each time row as shown by the red box above in ANSYS® Mechanical.
Definition of Force values that changes with time for each X, Y, and Z components is very easy as that in ANSYS® Mechanical. So you can create very realistic physical models in ANSYS® Mechanical with this principle.
