 As shown in the previous figure, two squares are crushed by a compression pressure and a contact tool that moves downwards by $2 \; dy$.  In the case on the left, the traditional ''Traction2DElement'' is used, while the new ''ContactTraction2DElement'' is used on the right.  The ''ContactTraction2DElement'' works correctly, if the total force on node $P_{14}$ along $\mathbf{y}$ is equal to the contact force along $\mathbf{y}$ at the end of the computation, i.e. that the traction force has been set to zero for the node in contact.  To check this equality, the difference between both forces (total and contact) is computed in the extractor ''diffTotalAndContactForceInCase2'' The results of the cases with the ''Traction2DElement'' and the ''ContactTraction2DElement'' are also compared by computing the differences of the total force along $\mathbf{y}$ at the nodes $P_{4}$ and $P_{14}$ in the extractor ''diffTotalForcesBetween2Cases'' This difference should be different from 0, unlike the previous one. As shown in the previous figure, two squares are crushed by a compression pressure and a contact tool that moves downwards by $2 \; dy$.  In the case on the left, the traditional ''Traction2DElement'' is used, while the new ''ContactTraction2DElement'' is used on the right.  The ''ContactTraction2DElement'' works correctly, if the total force on node $P_{14}$ along $\mathbf{y}$ is equal to the contact force along $\mathbf{y}$ at the end of the computation, i.e. that the traction force has been set to zero for the node in contact.  To check this equality, the difference between both forces (total and contact) is computed in the extractor ''diffTotalAndContactForceInCase2'' The results of the cases with the ''Traction2DElement'' and the ''ContactTraction2DElement'' are also compared by computing the differences of the total force along $\mathbf{y}$ at the nodes $P_{4}$ and $P_{14}$ in the extractor ''diffTotalForcesBetween2Cases'' This difference should be different from 0, unlike the previous one.
