  • Explosion and shock often involve large deformation,interface treatment between multi-material and strong discontinuity.The Eulerian method has advantages for solving these problems.In parallel computation of the Eulerian method,the physical quantities of the computaional cells do not change before the disturbance reaches to these cells.Computational efficiency is low when using fixed partition because of load imbalance.To solve this problem,a dynamic parallel method in which the computation domain expands with disturbance was used.The dynamic parallel program was designed based on the generally used MPI model.The numerical test of dynamic parallel program agrees well with that of the original parallel program,also agrees with actual situation.
