Linear Elasticity
=================
Only the constant stiffness matrix *WCC* is needed for the formulation.

.. literalinclude:: ./nvi_LinearElasticity_0.cpp

Linear Elasticity solved as non-linear
--------------------------------------
We solve the same problem but this time considering it as non-linear.
We need to give the formulation of the residual, even it is null.
The Newton algorithm shall convice us it is so.

.. literalinclude:: ./nvi_LinearElasticity_1.cpp
