- <CONCEPT>using distributed arrays;</CONCEPT> Bratu nonlinear PDE in 3d.
  We solve the Bratu (SFI - solid fuel ignition) problem in a 3D rectangular
  domain, using distributed arrays (DAs) to partition the parallel grid.
- <CONCEPT>using distributed arrays;</CONCEPT> 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 <lid>, where <lid> = dimensionless velocity of lid
  -grashof <gr>, where <gr> = dimensionless temperature gradent
  -prandtl <pr>, where <pr> = dimensionless thermal/momentum diffusity ratio
  -contours : draw contour plots of solution
