This research aims at reducing the time required to generate computational grid for inviscid as well as viscous flow simulations. The method is based on hexahedra grid method, as the extension of Cartesian grid method. As the result, the method inherits significant advantages of Cartesian grid: it is automatic and fast. Because an efficient viscous flow simulation requires grid with high aspect ratio near solid surface, a hybrid with prismatic grid is necessary. The hexahedra grid extends naturally to this approach, because there is consistency in grid topology (both Cartesian and prismatic grids have the same hexahedral shape). The main idea of the method is as follows: construct Cartesian grid, remove the cells near solid surface, and construct hexahedral cells based on the Cartesian cells\u0027 faces toward the surface. Note that both grids are not constructed from the solid surface. This leads to another advantage: the method is not sensitive to defects in solid surface (e.g. crack, overlap), because it actually reconstruct the solid surface grid. However, because of the way the hexahedral cells are constructed (simple projection from Cartesian grid cells\u0027 faces toward solid surface), there is a disadvantage: it can not capture sharp concave features.

This research aims at reducing the time required to generate computational grid for inviscid as well as viscous flow simulations. The method is based on hexahedra grid method, as the extension of Cartesian grid method. As the result, the method inherits significant advantages of Cartesian grid: it is automatic and fast. Because an efficient viscous flow simulation requires grid with high aspect ratio near solid surface, a hybrid with prismatic grid is necessary.
