| Black-box Multigrid Solvers (S. Klasky) | Equations that routines will solve Lhuh = fh, "black-box" calling interface with multigrid flavors available |
| Boson Star Application (R. Guenther) | Solves self-gravitating time-dependent Schrodinger equation in three spatial dimensions, with line-multigrid solvers used for update of Schrodinger field |
| Texas Black Hole Evolution Code (TCODE) (R. Correll & S. Klasky) | Black hole evolution code with leap frog time updates and second order methods at outer boundary replaced by first order methods |
| 2D Laser-Plasma Interaction Fluid Code (D. Fisher & S. Klasky) | Models the wakefields of a very short high-intensity laser pulse interacting with a plasma in a moving frame coordinate system, Lax Wendroff time updates, and 2D multigrid using a point-wise smoothing method |
Structured Adaptive Mesh Refinement (SAMR) Applications
| Application | Description |
| Scalarwave 2D/ Scalarwave 3D | Numerical relativity application (aka
NumRel 2D/ NumRel 3D) is a coupled set of partial differential
equations. Equations can be divided into two classes: elliptic (Laplace
equation-like) constraint equations which must be satisfied at each
time, and coupled hyperbolic (Wave equation-like) equations describing
time evolution. This kernel is part of the Cactus numerical relativity
toolkit. http://www.cactuscode.org |
| Buckley-Leverette 2D/ Buckley-Leverette 3D | Buckley-Leverette model is used in
Oil-Water Flow Simulation (OWFS) software system for simulation of
hydrocarbon pollution in aquifers. OWFS provides for layer-by-layer
modeling of oil-water mixture in confined aquifers with regard to
discharge/recharge, infiltration, interaction with surface water
bodies and drainage systems, discharge into springs and leakage
between layers. This kernel is taken from the IPARS reservoir
simulation toolkit developed at the Center for Subsurface Modeling at
University of Texas at Austin. http://www.ticam.utexas.edu/CSM/ACTI/ipars.html |
| RM 2D/ RM3D | 2/3-dimensional compressible
turbulence application solving the Richtmyer-Meshkov instability. This
application kernel is part of the virtual test facility developed
at the ASCI/ASAP Center at California Institute of Technology. The
Richtmyer-Meshkov instability is a fingering instability which occurs
at a material interface accelerated by a shock wave. This instability
plays an important role in the studies of supernova and inertial
confinement fusion. http://www.cacr.caltech.edu/ASAP |
| EnoAMR 2D | 2-dimensional application in
computational fluid dynamics that addresses the forward facing step
problem, describing what happens when a step is instantaneously risen
in a supersonic flow. The application/simulation has several features
including bow shock, Mach stem, contact discontinuity, and a numerical
boundary. EnoAMR 2D is also part of the virtual test facility
developed at the ASCI/ASAP Center at Caltech. http://www.cacr.caltech.edu/ASAP |
