Data Process and Domain Decomposition for 3D Unstructured Hybrid Mesh

Advanced techniques of data structure for 3D unstructured hybrid mesh domain decomposition and sub-domain display are presented.Aiming at higher computational accuracy,the unstructured hybrid mesh and the distributed parallel computation are used in 3D complex flow field simulation,the combination of these two techniques often causes difficulties in data structure and sub-domain definition because of the non-unification of mesh elements.The difficulties are discussed,a software call the AMD is developed and used in 3D unstructured hybrid mesh decomposition.Numerical tests show that the software AMD has robustness,high automatization and generalization.
