Hybrid Unstructured Mesh Deformation Based on Massive Parallel Processors

According to radial basis functions, the greedy method and the subspace method are used to develop a deformation solver for hybrid unstructured mesh. The solver is constructed with massive parallel processors to improve the deformation efficiency of complex boundary. ONERA M6 wing of million mesh magnitudes and X48B flying wing of ten million mesh magnitudes are selected as test cases. The parallel acceleration, robustness and efficiency of the solver are validated and compared with different CPU cores and basis functions. The results indicate that the mesh quality can be guaranteed after deformation, and the deformation efficiency can be increased more than 80 times with massive parallel system.
