DMDA

using distributed arrays; Bratu nonlinear PDE in 3d.
We solve the Bratu (SFI - solid fuel ignition) problem in a 3D rectangular
domain, using distributed arrays (DMDAs) to partition the parallel grid.

using distributed arrays; Nonlinear driven cavity with multigrid in 2d.

The 2D driven cavity problem is solved in a velocity-vorticity formulation.
The flow can be driven with the lid or with bouyancy or both:
-lidvelocity &ltlid&gt, where &ltlid&gt = dimensionless velocity of lid
-grashof &ltgr&gt, where &ltgr&gt = dimensionless temperature gradent
-prandtl &ltpr&gt, where &ltpr&gt = dimensionless thermal/momentum diffusity ratio
-contours : draw contour plots of solution

using distributed arrays Nonlinear Radiative Transport PDE with multigrid in 2d.
Uses 2-dimensional distributed arrays.
A 2-dim simplified Radiative Transport test problem is used, with analytic Jacobian.

Solves the linear systems via multilevel methods
