The discretization is called discrete (or discretized) model, while the original differential equation is called continuous model. The properties of both models are expected to be of exact coincidence, but there is always some inconsistency between them. In such a situation, we need to know the inconsistency in order to understand what a result of numerical computation means. Otherwise we might misunderstand it to regard a specific behavior of numerical solution coming from the property of discrete model but not from that of continuous one as a part of behavior of the original equation's solution. Here we show some trial to analyze the numerical instability that occurs in numerical calculation of shock waves, where occurs a typical example of inconsistency between the continuous and discrete models.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
