Assigning Forces in ANSYS Mechanical – Illustrated Explanation

Here, we will show you how to assign a force to the surfaces or other features of ANSYS Mechanical parts. In finite elements analysis, force assignation to a part to analyze is a boundary condition. So specifying boundary conditions is a very important thing to obtain a very correct finite element analysis. You will learn about how to assign forces to the various features of parts such as edges, vertexes, and faces.

How to Assign Forces to Parts in ANSYS Mechanical?

To assign a force to your part in ANSYS Mechanical, you need to open the Mechanical interface. In this Mechanical interface, you need to right-click on your analysis system 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 as shown by the blue arrow. The geometry selection is done by the Geometry tab in the force assignation command as shown by the red arrow. When you select the face to apply force, click apply in the Geometry tab in ANSYS Mechanical.

The assignation of force value is could be done by vector or components. You select one of these methods as shown by the red box above to assign your force value in ANSYS Mechanical. For example, we selected to define our force value as components in ANSYS Mechanical.

We assigned our force to the top face of the parts by entering 500 Newton values to each X, Y, and Z component as the red box above. Then you can see the direction of the defined force as the red arrow according to the values that entered by you to the ANSYS Mechanical.

Also, you can assign force by selecting the Vectors method in ANSYS Mechanical that you need only define a force value and then define a vector from the features of the part in ANSYS Mechanical.


Finally, the definition of force in ANSYS® Mechanical is as simple as that.

So, do not forget to leave your comments and questions below about the definition of force in ANSYS Mechanical.
