#### Elements in the Solid Mechanics Application

This application implements only volumetric or surface finite elements. This is the 3D solids and the simplified 2D models representing the same volumetric domain.

Most of the common finite elements for solid mechanics are formulated in displacements. The current developments give the displacement-based elememts avaliable in the application and also some hybrid dislacement-pressure based elements. The last ones are useful for the treatment of the material incompressibility.
