To execute this test:
1/ Make the mesh on the frontal interactively:
ElmerGrid 1 2 mesh_B.grd
(should create the directory mesh_B/ and mesh.* files inside)
2/ Run the FE simulations :
! For the Glen's law in the distrib
ElmerSolver test_glenDistrib.sif
! For the MATC definition of the Glen's law
ElmerSolver test_glenMATC.sif
Both should give the same results. Note the activation of the Newton linearization
which allows a very fast convergence of the non-linear iteration down to 1.0e-8
