Discretization of the two-dimensional square domain: (a) A Neohookean material in a square domain ($1\times 1$) under no slip (bottom edge), no traction (side walls), and vertical displacement of $20\%$ (top edge). The shear modulus of $\mu =100\mathrm{Pa}$ was used. (b) Number of elements and degrees of freedom (DOFS) in each discretization for the ($†$) LM/PL and ($‡$) weakly penalized/penalty methods.
