+Note that the cantilever geometry is stored as the original undeformed geometry and a displacement field. In paraview, the geometry can be deformed to match the flow domain using the 'Warp by Vector' filter.

 #### Relaxing the computation
 
 In order to increase the speed of convergence, it is normally a good option to apply a relaxation
