A novel grid-stitching algorithm has been developed for generating Cartesian-like grids for viscous flow calculations. A grid is generated by recursive division of Cartesian cells. Unlike the conventional Cartesian-mesh calculations that involve unit aspect ratio cells, stretching is used to get the high aspect ratio cells and smooth grid near the body. The grid data are collected in an unstructured format. This novel approach, along with an unstructured mesh-based flow solver (HIFUN-2D, developed in-house), has been successfully used for numerical simulations. This grid is successfully used for Euler and laminar flowcomputations. Partial success has been achieved for turbulent flow simulations.
