EAGLE WITH REAL-TIME INTERACTIVE GRID MANIPULATION

THE BASIS FOR REAL-TIME INTERACTIVE GRID MANIPULATION WOULD BE ESTABLISHED WITHIN THE EAGLE CODE. THIS WOULD BRING THE INTERACTION DIRECTLY INTO THE EXECUTION PHASE OF GRID GENERATION AND WOULD THEREBY REPRESENT A SIGNIFICANT DEPARTURE FROM OTHER INTERACTIVE GRID GENERATION CODES. ALTOGETHER, THE PROPOSED DEVELOPMENT WOULD COMPLEMENT THOSE OTHER INTERACTIVE CONSTRUCTIONS AND WOULD PROCEED WELL BEYOND THEM. IN ESSENSE, THE MOST SOPHISTICATED 3D BLOCKSTRUCTURED GRID GENERATION CODE, EAGLE, WOULD BE COMBINED WITH THE MOST FLEXIBLE ALGEBRAIC GRID GENERATION SCHEME, THE "CONTROL POINT FORM OF ALGEBRAIC GRID GENERATION". THE EAGLE CODE WAS DEVELOPED AT THE AIR FORCE ARMAMENT LABORATORY, EGLIN AFB, AND MISSISSIPPI STATE UNIVERSITY. THE "CONTROL POINT FORM" WAS DEVELOPED AT COLUMBIA UNIVERSITY. WITH THIS COMBINATION, THERE WOULD BE THE CAPABILITY TO PERFORM LOCAL MANIPULATIONS OF THE GRID. THAT IS, THE GRID COULD BE ALTERED IN ONE REGION TO MEET SOME GRID CLUSTERING OR STRUCTURAL DEMANDS OR TO CHANGE THE SHAPE OF SOME BODY. DURING THAT PROCESS, THE REMAINING GRID WOULD REMAIN INTACT AND UNALTERED. THIS ALTERATION COULD FUNCTION AS EITHER A POST-PROCESSOR OR AN EXISTING GRID OR AS A PART OF AN INITIAL CONSTRUCTION OF THE GIRD.
