Added Mass, Interface
The Added Mass, Interface node is available for boundaries and edges 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 inertia is added at the selected interfaces between the material layers.
Layer Selection
Select the interfaces between the layers to which the added mass contribution is to be applied.
