Abstract:

Compressible fluid numerical simulation is widely used in applications such as aircraft shape optimization design, urban disaster prevention and so on. In the analysis and design of numerical methods, the high efficiency of algorithms is a key to practical applications. Based on the Euler equations, this report will discuss the improvement of algorithm efficiency for a class of adaptive mesh methods, including the data structure used to support the high-efficiency realization of grid local encryption, reliable and efficient error estimation methods, and the implementation of algorithms, program implementation, etc. Finally, we will provide numerical experiments to demonstrate the effectiveness of the algorithm.
