Abstract:

Computation based on the SAMR mesh gets the same simulation results as that on the global refinement mesh,but the former only needs less cells and computation time.A parallel SAMR program for the simulation of hydrodynamic instability in inertial confinement fusion is developed on JASMIN.And an implosion experiment is simulated on hundreds of processors.Both simulation results and performance analysis demonstrate the correctness and high efficiency of the code.

Key words: adaptive computation;parallel computation;SAMR, JASMIN
