  • 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 (DAs) 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 <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
  • using distributed arrays; Grad-Shafranov solver for one dimensional CHI equilibrium.
  • using distributed arrays; XXXXX with multigrid and timestepping 2d.
