Optimization and performance analysis for code of finite volume lattice Boltzmann method

Finite volume lattice Boltzmann method(LBM) can extend the standard LBM to unstructured mesh,but compared with standard LBM this method suffers from higher memory consumption and poorer computational performance.In order to solve this problem,the improvement process used the methods of optimizing evaluation order and simplifying calculating equation.Scientific analysis and experimental results demonstrate that the improved algorithm results in lower memory usage without additional computation,and in some conditions it reduces much computation.
