SHEAR
======================================================================

2-D shear test with linear quadrilateral cells.


          ----------
          |        |
Uy=-1.0 m |        | Uy=+1.0m
          |        |
          |        |
          ----------


Dirichlet boundary conditions
  Ux(   0,y) =  0.0
  Uy(   0,y) = -1.0 m
  Ux(+400,y) =  0.0
  Uy(+400,y) = +1.0 m

Analytical solution
  Ux(x,y) = 0
  Uy(x,y) = -0.0025 * x

          ----------


Dirichlet boundary conditions
  Ux(   0,y) =  0.0
  Uy(   0,y) = -0.5 m
  Ux(+400,y) =  0.0
  Uy(+400,y) = +0.5 m

Analytical solution
  Ux(x<0,y) = -0.5 m
  Ux(x>0,y) = +0.5 m
  Uy = 0.0

======================================================================
DISLOCATION2
======================================================================

2-D dislocation test with linear quadrilateral cells with 2
faults. One is right-lateral and one is left-lateral to cause the
middle section to move 1.0 m to the right.


           Ux=0

         |        |
         ----------
           Ux=0


Dirichlet boundary conditions
  Ux(x,+400) =  0.0
  Uy(x,+400) =  0.0
  Ux(x,-400) =  0.0
  Uy(x,-400) =  0.0

Analytical solution
  Ux(x,-100<y<+100) = +1.0 m
  Ux(x,-100>y) = 0.0
  Ux(x,+100<y) = 0.0
  Uy = 0.0
