What is it about?
As fluid dynamic simulations get larger, traditional rules-of-thumb on grid construction fail as problem complexity outpaces the performance of supercomputers. An alternative derivation is presented that reduces the cost of the simulations but still retains validity for hypersonic flows

Why is it important?
Large Eddy Simulations are just now beginning to reach into the length scales representative of flight, but the time scales introduced make calculations prohibitively expensive. The proposed method allows for at least an order of magnitude increase in the simulation timestep.
Perspectives
This is my initial publication on what has become my dissertation. The model has continued to expand and be tested, but the underlying framework presented here is fundamental to the work.
