In order to e xecute various finite-difference method applications on large-scale parallel computers with a reasonable cost of computer resources, a framework using an adaptive mesh refinement (AMR) technique has been developed. AMR can realize high -resolution simulations while saving computer resources by generating and removing hierarchica l grids dynamically. In the AMR frame work, a dynamic domain decomposition (DDD) technique, as a dynamic load balancing method, is also implemented to correct the computational load imbalance between each process associated with parallelization. By performing a 3D AM R test simulation, it is confirmed that dynamic load balancing can be achieved and execution time can be reduced by introducing the DDD technique
