It is a very useful tool in ANSYS® Mechanical to add or define point masses and inertia effects to a selected geometry. You can define point mass and inertia effect wherever you want to a geometry. It is a very basic process to do it. So in this article, we will show how to add Point Mass and Inertia to geometry in ANSYS® Mechanical. It is a very important boundary condition in some finite element models of physical situations.

How To Add Point Mass To A Geometry In ANSYS® Mechanical?
To add Point Mass and inertia effects to geometry in ANSYS® Mechanical, right-click on models that inside the geometry tab in Mechanical Tree, hover your mouse on the ‘Insert’ tab as shown by the red arrow then click on ‘Point Mass’ as shown in the red box.
For example, we want to add a point mass value to these two faces selected as above. After selection of geometric features such as vertexes, faces, or edges, click on the ‘Apply’ button in the ‘Details’ section as shown by the red arrow above in ANSYS® Mechanical.
In the ‘Location’ section, you can define the point mass location of the selected geometries as shown by the red box above. Then click ‘Apply’ after the selection.
Also, you can enter the X, Y, and Z locations manually from the section above the ‘Location’ tab.
In the ‘Definition’ tab, enter your mass and mass moment of inertia values in every coordinate as shown by the red box above. These parameters will be defined in the selected mass location in ANSYS® Mechanical.
You can select a material behavior such as; Rigid, Deformable, Coupled, or Beam as shown above in ANSYS® Mechanical.
As you can see above, the point mass value is defined as shown by the green box and arrow above in ANSYS® Mechanical.
Conclusion
So you understand that definition of point mass and mass moment inertia values in each coordinate is very basic in ANSYS® Mechanical.
