Detailed Description

Stationay Elasicity model with homogeneous Dirichlet boundary conditions.

The code has the follows the features:

• Stationary Elasticity equations
• Homogeneous Dirichlet boundary condition
• Exact polynomial solution
• Newton solver
• Multigrid preconditioner with Schwarz-smoother

Boundary conditions

We impose the displacement on the left and on the right edge of the square domain. In particular:

\begin{align*} u_x &=-1 \qquad\qquad & \text{on}\ x=0, \\ u_x &= 1 \qquad\qquad & \text{on}\ x=1, \end{align*}
