Hyung-Jun Kim, Auteur ; Lee, Jin Woo, Auteur ; Yong-Sik Cho, Auteur |The Cartesian cut-cell method can be used to represent irregular and complex computational domains with less computational efforts by cutting the grid cells on the boundary surfaces in a background uniform Cartesian mesh. In this study, a modifi[...]

Dae-Hong Kim, Auteur ; Keh - Han Wang, Éditeur scientifique ; Kim, Woo-Gu ; Yong-Sik Cho, Auteur |A numerical model describing two-dimensional fluid motions has been developed on an unstructured grid system. By using a fractional step method, a two-dimensional problem governed by the two-dimensional shallow-water equations is treated as two[...]
