Mixed 3D Solid Finite Element
In this example we generate a three-dimensional finite element to analyze hyperelastic solid problems. The element has the following characteristics:
  • Hexahedral topology
  • Eight nodes
  • Isoparametric mapping from reference to actual frame
  • Global unknowns that are displacements of the nodes
  • Enhanced strain formulation to improve shear and volumetric locking response
Minimization of Free Energy
Here we consider steady-state heat conduction on a three-dimensional domain. The solution of the same physical problem can be obtained via multiple methods, shown here as a minimum of the free energy of the system. The domain of the example is a cube filled with water and containing a constant heat source. The upper surface is isolated so that there is no heat flow over the boundary. On all other sides a constant temperature is maintained. The task is to calculate the temperature distribution inside the cube.
