  1. Because euler equations have disconnected solutions named shock wave in numerical simulation flow field, and to make sure the disconnected solutions not expanding or vanishing among parallel computation sub - domains, there must be certain connections in the numerical value variable among the sub - domains

    由於歐拉方程數值模擬求解流場區域內間斷解即激,而計算流體力學并行數值計算是分區的基礎上進行的,為了使流場區域內的間斷解因分區并行計算而或消失,分區之間的數值變量必然著一定的聯系。
