          <datacite:description descriptionType="Abstract">非構造格子による2次元格子形成アルゴリズムを示した。本アルゴリズムでは非構造格子形成の自動化が可能であるが、一連の境界点とか各境界の特性ような最小限のユーザ入力が要求される。格子形成の自動化を実現するには2手順が必要で、1つは格子点を自動的に生成することで、もう1つは生成格子点を用いて領域の3角形分割を行うことである。この2手順の実現にはDelaunayの3角形分割を用いる。2次元Euler方程式を解くセルセンタ型有限体積法も開発した。このソルバでは対流項を差分するMUSCLアプローチによるAUSMDV法と時間積分のためのEuler法を用いる。MUSCLアプローチを対照するため数値シミュレーションを実行した。適合格子法を用いた計算結果も示した。</datacite:description>
          <datacite:description descriptionType="Other">An algorithm to generate two-dimensional unstructured grids is presented. This algorithm makes it possible to generate unstructured grid automatically. Therefore only minimum user input is required such as a set of boundary points and the character of each boundary. Two properties are necessary in order to realize automatic grid generation. One is a generating grid points automatically and the other is a triangulation of the region using the generated grid points. The Delaunay triangulation is used to realize these two properties. A Cell-centered finite volume solver is also developed to solve the two-dimensional Euler equations. This solver uses the AUSMDV (Advection Upstream Splitting Method flux Difference and flux Vector) scheme with MUSCL (Monotone Upstream Centered Scheme for Conservation Laws) approach for convective term differencing and Euler explicit scheme for time integration. Numerical simulations are carried out in order to compare some MUSCL approaches. Some results of calculations using the grid adapting method is also presented.</datacite:description>
