Abstract

Abstract: An adaptive time integration algorithm is proposed for ADE(alternating direction explicit based on dimension splitting) scheme.Based on the algorithm,a parallel adaptive program for multi-material hydrodynamics is developed on JASMIN.An implosion experiment in ICF(inertial confinement fusion) is simulated on 512 processors.Both simulation results and performance analysis demonstrate correctness and efficiency of the algorithm and the code.

Key words: adaptive computation, parallel computation, ADE scheme, JASMIN
