Elements in the Solid Mechanics Application

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

Most of the common finite elements for solid mechanics are formulated in displacements. The application is currently implementing the displacement-based elememts and also some hybrid displacement-pressure based elements. The last ones are useful for the treatment of the material incompressibility.
