static char help[] = "The variable-viscosity Stokes Problem in 2d with finite elements.\n\
We solve the Stokes problem in a square domain\n\
and compare against exact solutions from Mirko Velic.\n\n\n";

/* We discretize the variable-viscosity Stokes problem using the finite element method on an unstructured mesh. The weak form equations are
\begin{align*}
  (\nabla v, \mu (\nabla u + {\nabla u}^T)) - (\nabla\cdot v, p) + (v, f) &= 0 \\
  (q, \nabla\cdot u)                                                      &= 0
\end{align*}
Free slip conditions for velocity are enforced on every wall. The pressure is constrained to have zero integral over the domain.

  SolKxSolution - Exact Stokes solutions for exponentially varying viscosity

 Input Parameters:
+ pos   - The (x,z) coordinate at which to evaluate the solution
. n     - The constant defining the x-dependence of the forcing function
. m     - The constant defining the z-dependence of the forcing function
- B     - The viscosity coefficient

  Output Parameters:
+ vel   - The (x,z)-velocity at (x,z), or NULL
. p     - The pressure at (x,z), or NULL
. s     - The total stress (sigma_xx, sigma_xz, sigma_zz) at (x,z), or NULL
. gamma - The strain rate, or NULL
- mu    - The viscosity at (x,z), or NULL

  Note:
$  The domain is the square 0 <= x,z <= 1. We solve the Stokes equation for incompressible flow with free-slip boundary
$  conditions everywhere. The forcing term f is given by
$
$    fx = 0
$    fz = sigma*sin(km*z)*cos(kn*x)
$
$  where
$
$    km = m*Pi (m may be non-integral)
$    kn = n*Pi
$
$  meaning that the density rho is -sigma*sin(km*z)*cos(kn*x). Here we set sigma = 1.
$  The viscosity eta is exp(2*B*x).

+ vel   - The (x,z)-velocity at (x,z), or NULL
. p     - The pressure at (x,z), or NULL
. s     - The total stress (sigma_xx, sigma_xz, sigma_zz) at (x,z), or NULL
. gamma - The strain rate, or NULL
- mu    - The viscosity at (x,z), or NULL

  Note:
$  The domain is the square 0 <= x,z <= 1. We solve the Stokes equation for incompressible flow with free-slip boundary
$  conditions everywhere. The forcing term f is given by
$
$    fx = 0
$    fz = sigma*sin(km*z)*cos(kn*x)
$
$  where
$
$    km = m*Pi (m may be non-integral)
$    kn = n*Pi
$
$  meaning that the density rho is -sigma*sin(km*z)*cos(kn*x). Here we set sigma = 1.
$  The viscosity eta jumps from etaA to etaB at x = xc.
