Reservoir Simulation

IPARS++ (Center for Subsurface Modeling, University of Texas at Austin)

DAGH has been in integrated with IPARS (Integrated Parallel Accurate Reservoir Simulator) to provide a PSE for parallel adaptive porous media and reservoir simulations.

Numerical Relativty

Binary Black-Hole Coalescence (Binary Black-Hole Grand Challenge Alliance)

The goal of this project is to develop numerical codes to solve the problem of the 3D spiraling coalescence of two black holes. This is a fundamental problem in relativity and astrophysics, as colliding black holes are among the most promising sources for generating gravitational waves that may be detected by the turn of the century. The Binary Black-Hole Grand Challenge Alliance is an NSF funded collaboration among physicists and computer scientists at eight institutions.

Relativistic Hydrodynamics

Neutron Star Grand Challenge

Study of the coalescence of neutron star binaries.

Relativistic Hydrodynamics (Peter Anninos, NCSA, UIUC)

Fully general relativistic hydrodyamics code, written specifically to compute the flow of gas around strong field gravity sources such as black holes. At the moment it's best suited for applications in which the gas energy does not significantly alter or influence the stronger gravity source, although fully self-consistent feedback by coupling the hydro code with either NCSA/Max-Planck-Intitut G or NewAge are currently beeing added.

Newtonian & General Relativistic Hydrodynamics (Prof. Jose Maria Iba\~nez, Astrophysics Department, University of Valencia, Spain)

DAGH is being used, together with the Framework (PSE), for the development of newtonian and general relativistic hydrodynamics codes to study supernova collapse, neutron binary coalescence and other astrophysical problems.

Newtonian & General Relativistic Hydrodynamics (Prof. Carles Bona, Gravitation Group, Physics Department, University of the Balearic Islands, Palma de Mallorca, Spain)

DAGH is being used, together with the Framework (PSE), for the development of codes to solve the full Einstein Equations and study the structure of spacetime, the formation of singularities and the gravitational wave emission during the collision of black holes.
