# Defining Remote Force That Changes With Time In ANSYS® Mechanical(Illustrated Expression)

In this article, we will show you how to define a Remote Force to a geometry that changes with time in ANSYS® Mechanical. You can assign Remote Forces from Tabular Data that different force values at each time step. So you can define very realistic force values according to the time as real physical systems. Remote forces are boundary conditions in finite element analysis(FEA) so it is very important to define them correctly to obtain realistic results.

## How To Define Remote Forces That Change With Time In ANSYS® Mechanical?

To add or apply Remote Force that changes with time on geometry in ANSYS® Mechanical, you need to right-click on the analysis system(Static Structural in here) and hover the cursor on the Insert button as shown by the red arrow above. Click on Remote Force as shown by the red box from the list.

Select the geometric feature to apply Remote Force that changes with time then clicks Apply on the Geometry tab as shown by the red arrow above.

You could define the remote force’s place in 3D space by entering X, Y and Z coordinates in ANSYS® Mechanical. We entered 5, 5, and 10 mm of coordinates respectively.

You can define Remote Force as Components or Vector. We will define it as a Vector in this example. Click on the little pop-up menu as shown by the red arrow above then click on the Tabular(Time) selection as shown in the red box to define Remote Force that changes with time in ANSYS® Mechanical.

You can add a time as shown by the red arrow above as Tabular Data row, then you can enter a force value next to that time as shown in the red box above to create Remote Force that changes with time in ANSYS® Workbench.

Click on the direction section and select a direction as shown in the red box above then click on the Apply button as shown by the red arrow.

## Conclusion

The application of a Remote Force that changes with time is easy like that.
