Parallel Implicit Solvers for Radiation Transport Systems

This work is part of a collaborative project between ICASE and Old Dominion University
funded by the US Department of Energy (DOE) as an ASCI Level 2 Grant.
 
 

Principal Investigators are:
 

  •   David Keyes (Old Dominion University and ICASE)
  •  Alex Pothen (Old Dominion University and ICASE)
  •  Dimitri Mavriplis (ICASE)

    •  

     
     
     

    An overview of the project, is described in the ICASE Quarterly Article entitled:

    ParallelParallel Implicit Solvers for Radiation Transport Systems Under the DOE ASCI Program
     
     


     
     

    This page describes some of the highlights of the work
    performed by myself (Dimitri Mavriplis) on this project.

    For a more complete description of this project,
    the official web page for this project describes the project in more detail
    and the work done by all PIs and research assistants.
