Domain, Boundary, Edge, Point, and Pair Nodes for the Electromechanics Interface

	In general, to add a node, go to the Physics toolbar, no matter what operating system you are using. Subnodes are available by clicking the parent node and selecting it from the Attributes menu.

	The Linear Elastic Material Model or the Linear Elastic Dielectric nodes can be used to model electrostatically actuated structures. Use the Linear Elastic Material Model if the electric field is zero within the material itself and the Linear Elastic Dielectric if the field is nonzero. Other material models are provided with the physics interface to model, for example, the effect of packaging materials on the structure as a whole. These material models cannot be used in models of electrostatically actuated structures and should not be placed adjacent to domains with Electric Potential degrees of freedom.

	If you have the Nonlinear Structural Materials Module, other nonlinear materials are also available, as described in the Nonlinear Structural Materials User’s Guide. These nodes also override the Electrical Material Model node and then the Electromechanical Interface node also applies electrical forces to the surface of these materials automatically.
