Added Mass

The node is available for boundaries, edges, and points and can be used to supply inertia that is not part of the material itself. Such inertia does not need to be isotropic, in the sense that the inertial effects are not the same in all directions. The extra inertia is as a volumetric, boundary, or edge contribution to the selected material layers.

You can also add inertia to the interfaces between the material layers by using Added Mass, Interface.

Layer Selection

Select the material layers to which the added mass contribution is to be applied.
