# Defining Remote Force As A Time Function In ANSYS Mechanical(Illustrated Expression)

In this article of Mechanicalland, we will show you how to define Remote Force as a time function in ANSYS® Mechanical. As forces, Remote Force also can be assigned as a time-dependent function. This means that you can model the physical systems very realistically. Remote Force is a boundary condition in finite element analysis(FEA) that is very important to assign correctly.

## How To Define Time-Dependent Remote Force In ANSYS® Mechanical?

To add or apply time-dependent Remote Force 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 as a time-dependent function then click Apply on the Geometry tab as shown by the red arrow above.

You could define the time-dependent 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 and also you can select this from Define By section above. We selected Vector for our example here. Click on the little pop-up menu as shown by the green arrow above then click on Function as shown in the green box above to define time-dependent Remote Force in ANSYS® Mechanical.

From the Magnitude section of the Remote Force, you can enter the time function of Remote Force by using the variable of “time” as in the green box above. You can see the results of this function with changing time from the Tabular Data as shown by the green arrow.

Select the direction of Remote Force as a function format as shown in the green box above. Then click on the Apply button as shown by the green arrow in the Direction section.

Enter the segmentation of Tabular Data that will define the row number. The time between 0-1 second will be divided into the Number Of Segments. You can see the result of the number of segments on Tabular Data as shown by the green arrow above.

You can see the time values on each row of Tabular Data as shown in the green box above, also you can see the Force values that are defined according to these time values from the function that you defined.

## Conclusion

As you can see the definition of time-dependent remote force is very easy in ANSYS® Mechanical.
