Damping

Use the 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 subnode are ignored.

This section is only present when this node is added under node.

Select the layer or layers for which this damping model is to be used.

Table 5-16: Layer Selections; Damping
Selection	Use All Layers	Selection of Individual Layers
Boundary	Same as parent selection when the node is added.	When Use all layers is not selected. Only a subset of the layers selected in the parent can be selected.

When the damping model differs between layers, you will need to add several nodes with different layer selections. If the model is the same, and only the material data values differ, you can for most models use a single node with . The data for each layer is then received from global nodes.

All other settings for the node are described in the documentation for Damping in the Solid Mechanics interface.

For a general description of layer and interface selections, see The Shell Properties and Interface Selection Sections.

You can describe damping values with a through-thickness variation by explicitly or implicitly using expressions containing the extra dimension coordinate as described in Using the Extra Dimension Coordinates.
