Adding Point Mass To A Geometry In ANSYS Mechanical(Illustrated Expression)

It is 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 whereever you want to a geometry. It is very basci process to do it. So in this article we will show how to add Point Mass and Inertia to a geometry in ANSYS Mechanical. It is very important boundry condition in some finite element models of physical situations.

How To Add Point Mass To A Geometry In ANSYS Mechanical?

Click on Point Mass in ANSYS Mechanical.

To add Point Mass and inertia effects to a geometry in ANSYS Mechanical, right click on models that inside the geometry tab in Mechanical Tree, hover your mouse on ‘Insert’ tab as shown by red arrow then click on ‘Point Mass’ as shown in red box.

Selecting the geometries for mass definition.

For example we want to add a point mass value to these two faces that selected as above. After selection of geometric features such as vertexes, faces or edges, click on ‘Apply’ button in ‘Details’ section as shown by red arrow above in ANSYS Mechanical.

Select the mass location in ANSYS Mechanical.

At ‘Location’ section, you can define the point mass location of the selected geometries as shown by red box above. Then click ‘Apply’ after the selection.

Also you can enter the X, Y and Z locations manually from the section that above the ‘Location’ tab.

Enter the Mass and Mass Moment Of Inertia values.

In the ‘Definition’ tab, enter your mass and mass moment of inertia values in every coordinates as shown by red box above. These parameters will be defined on the selected mass location in ANSYS Mechanical.

Select the material behavior.

You can select a material behavior such as; Rigid, Deformable, Coupled or Beam as shown above in ANSYS Mechanical.

Point Mass value is defined in ANSYS Mechanical.

As you can see above, the point mass value is defined as shown by green box and arrow above inb ANSYS Mechanical.

So you understand that definition of point mass and mass moment inertia values in each coordinates is very basic in ANSYS Mechanical.
