内容記述 | An adaptive grid generation method using elliptic equations is developed for compressible flows. In the present adaptive method, a control function is connected with a weight function, which controls the grid density. Thus, the weight function is important to generate the adaptive grid of high quality. A new approach for making the weight function is tried in this paper. To construct the weight function, a combination of the actual distribution of a flow property with a fictitious distribution of an artificial property is used. The adaptive method is applied to many shocked-flow problems of one and two dimension. It is shown that the new weight function works well and the present adaptive method is promising for compressible flows, especially, shocked flows. | |||||
