+ step-44, contributed by Andrew McBride and Jean-Paul
+ Perlteret, demonstrates one approach to modelling large
+ deformations of nearly-incompressible elastic solids. The
+ elastic response is governed by a non-linear, hyperelastic
+ free-energy function. The geometrical response is also
+ nonlinear, i.e., the program considers finite deformations.

how to solve the obstacle problem. This problem describes
the deformation of a body subject to an inequality
constraint that arises from the fact that the deformation is
