Abstract
A new distributed parallel SPH programming scheme using AMR (adaptive mesh refinement) background grid is proposed, in which the size of a grid is decided based on maximal smoothed length of local particles. In detonation simulation, computational complexity of the new scheme is better than O(NlgN) which is the best order of magnitude in the previous methods. Several hypervelocity impact problems are simulated using the new SPH scheme with state equations or strength model. The simulation results are discussed comparison to experimental and computed results in other literature.
