摘要
分区计算是计算流体力学中处理复杂几何区域、多块物体相互运动和进行并行计算的一类重要方法.对分区算法、相关理论问题和一些数值现象进行了综述.
The basic principle of the muhiblock method is to split a computational domain into several smaller ones. It is frequently used to deal with complex geometry and in parallel computing. The basic multiblock method is described including the way of splitting and the interface conditions in matching solutions between adjacent subdomains. Then we describe how to use the muhiblock method to do parallel computing and how to analyze stability, convergence, conservation and uniqueness. Finally, an overview on stability, accuracy, convergence, conservation and uniqueness of a multiblock method is given.
