Damping
Use the Damping subnode to add several types of damping to the material model. Damping can be used in Time Dependent, Eigenfrequency, and Frequency Domain studies; for other study types the settings in the Damping subnode are ignored.
You can add the Damping subnode to the Linear Elastic Material, and Layered Linear Elastic Material.
All other settings for the Damping node are described in the documentation for Damping in the Solid Mechanics interface.
