摘要
A method of improving a 2D or 3D multiblock-structured mesh of an object that moves through a fluid medium, such as an aircraft. The method is used in the design of the object in connection with a defined analytical scheme, the mesh having been generated with rectangular (2D) or hexahedral (3D) blocks under constraints that may cause the mesh to include irregular blocks comprising the following steps: finding irregular blocks in the mesh; degenerating the irregular blocks merging contiguous edges or sides in one edge or side so that triangular (2D) or pentahedral (3D) blocks are formed and extending the modifications all along the blocks that are propagated; and generating several rectangular (2D) or hexahedral (3D) regular blocks inside the triangular (2D) or pentahedral (3D) blocks. A system for carrying out the method.
