The distributed mass definition feature of ANSYS® is a very useful thing that you can assign various mass values to various geometric features inside ANSYS® Mechanical. So mass value does not depend on the material properties because you can enter whatever you want. Mass is a very important boundary condition in finite element methods(FEM), definition of is correctly is very vital.
To add Distributed Mass 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 ‘Distributed Mass’ as shown in the red box.
After opening a Distributed Mass, select your geometric features such as bodies, faces, edges, vertexes, etc. In this example, we selected the three faces as above. After the selection of geometries, click on the ‘Apply’ button as shown by the red arrow above.
ou can define the distributed mass in two ways;
Total Mass: You can enter a mass value to the selected geometries in ANSYS® Mechanical.
Mass per Unit Area: You can define your mass per unit area, and the total mass is calculated according to your geometry’s area.
Enter a mass value as shown in red box above. The mass will be defined as shown by green arrow above.
The definition of Distributed Mass in ANSYS® Mechanical is simple like that.
