Improvements in Generating and Using Unstructured CFD Grids

Some recent and continuing efforts to develop a software system for simulations of flows in gas-turbine combustors by Computational Fluid Dynamics (CFD) have addressed such major issues as the integration of CAD (Computer Aided Design) data for grid generation purposes. The generation of coordinate grids for use in flow-field computations is a major issue due to its time-consuming nature. The direct use and import of CAD data is important so as to remain true to the geometry and to reduce the user time necessary in generating the computational grid.
