A pressure weighted method is proposed for numerical solution of the momentum equation in 2D Lagrangian hydrodynamic equations with heat conduction over quadrilateral mesh. It is equivalent to the usual circuit integral method when the mesh is regular. However, when the mesh deforms, it has some advantages over the circuit integral method. It is more accurate and can hold back the unphysical distortion of the Lagrange mesh.

The Monte Carlo method is used to simulate unsteady-state particle transport calculations. Due to the computational time existing obviously difference among the different steps and I/O percentage is rated high, it results in the parallel com-putation efficiency down if the fix processors are used in each step. So parallel I/O and the adaptive parallel algorithms are developed. The good results and high speedup are obtained.

In this paper, an adaptive mesh refinement technique is presented in numeri-cal solution of partial differential equations. Mainly including scanning function,refining/ derefine, and the method has been implemented based on unstructuregrid and in Lagrangian or in Eulerian. Results are very helpful to the study of thenumerical simulation of detonation and study of explosive performances.
