Development of an unstructured Cartesian flow solver

An anisotropic unstructured cartesian grid generator and a flow solver were developed for the compressible viscous flow. The grid generator assumes a body configuration given as a set of data points and generates automatically a computational cartesian grid with geometry adaptation. The cartesian flow solver employs an upwind high resolution shock capturing scheme with linear reconstruction to achieve globally second order accuracy. In order to render the flow solver capable of solving supersonic flows, a limiter function was incorporated in the reconstruction algorithm. A solution -based grid adaptation algorithm that employs the discrete wavelet transform was built in the developed flow solver and tested for several standard and non-standard test cases.
