Development of an Advanced Implicit Algorithm for MHD Computations on Parallel Supercomputers.
Abstract
The primary objective of this project is to develop an advanced algorithm for parallel supercomputers to model time- dependent magnetohydrodynamics (MHD) in all three dimensions. A production code with this algorithm will provide a valuable tool for the design and testing of plasma related technologies that are important to the Air Force and industry. Implementing the algorithm on parallel supercomputers will allow the detailed modeling of realistic plasmas in complex three-dimensional geometries. The algorithm incorporates an approximate Riemann solver with explicit diffusive terms. The system of equations is solved using an implicit lower-upper symmetric-Gauss-Seidel (LUSGS) relaxation method. A two-dimensional version of the algorithm has been developed, placed into a testhed code, modified to include viscous and resistive effects, and tested against known analytical problems. The algorithm has been benchmarked to the one-dimensional shock tube and two-dimensional fully-developed (unmagnetized) viscous flow and (magnetized) Hattmann flow. The algorithm has been implemented on a parallel architecture and parallelization strategies have been investigated.
