Initial Values
The Initial Values node adds initial values for the displacement and velocity fields. It can serve as an initial condition for a transient simulation or as an initial guess for a nonlinear analysis. In addition to the default Initial Values node always present in the interface, you can add more Initial Values nodes if needed.
Shell Properties
Select the material layers to which the initial values are to be applied.

Same as interface selection when the node is added.
In the default material node, the setting is alway inherited from the interface setting and cannot be changed.

•
All other settings for the Initial Values node are described in the documentation for Initial Values in the Solid Mechanics interface.

For a general description of layer and interface selections, see The Shell Properties and Interface Selection Sections.
•
You can provide material parameters with a through-thickness variation by explicitly or implicitly using expressions containing the extra dimension coordinate as described in Using the Extra Dimension Coordinates.
