Research abstract
STRUCTURED GRIDS HAVE BEEN USED IN THE CFD APPLICATIONS FOR OVER 20 YEARS. HOWEVER, IN RECENT YEARS, IT HAS BECOME APPARENT THAT STRUCTURED GRIDS ARE NOT FLEXIBLE ENOUGH FOR FLOWS OVER VERY COMPLEX DOMAINS. UNSTRUCTURED GRIDS ARE, THEREFORE, RECEIVING CONSIDERABLE ATTENTION. ALTHOUGH, THE USE OF THE UNSTRUCTURED GRIDS REMOVES THE GEOMETRICAL RESTRICTION OF STRUCTURED GRIDS, A PROBLEM THAT REMAINS IS THE EFFICIENT GENERATION OF THESE GRIDS-PARTICULARLY IN THREE-DIMENSIONS. IT IS PROPOSED TO DEVELOP A GRID GENERATION CAPABILITY WHICH, COMBINED WITH A FAST NEAR NEIGHBOR ALGORITHM, COULD REDUCE GRID GENERATION TIMES BY ANORDER OF MAGNITUDE COMPARED TO THE PRESENTLY AVAILABLE METHODS. IT IS ALSO PLANNED TO DEVELOP A MENU-DRIVEN GRID GENERATION ALGORITHM AND FAST INTERACTIVE GRAPHICS.
