Toyama International Conference Center), Toyama Japan, When the body-fitted coordinate system is adopted, some discretized forms of transform metrics break the freestream preservation which is so-called geometric conservation law (GCL). The GCL identities consist of surface closure law (SCL) and SCL) and volume conservation law (VCL), and the SCL identity is focused. One of the techniques for the discretization of spatial metrics is to rewrite the analytical expression of spatial metrics into asymmetric-conservative forms proposed by Thomas and Lombard, which are extended into symmetricconservative forms by Vinokur and Yee. In this research, we present the geometrical meanings of discretized symmetric-conservative forms with the use of any higher-order finite difference method., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0061958010, レポート番号: JAXA-SP-12-010}, pages = {55--60}, publisher = {宇宙航空研究開発機構(JAXA), Japan Aerospace Exploration Agency (JAXA)}, title = {有限差分法における保存型空間メトリックの空間対称性と幾何学的解釈}, volume = {JAXA-SP-12-010}, year = {2013} }
