| Abstract: | The body fitted coordinate (BFC) transformation equation is derived using the transformation equation, BFC grids of the molten pool area in twin roll strip casting process is generated. Orthogonality of the grids on the boundary is modified through adjusting source items. The universal equation in metallurgy transportation and the boundary conditions are transformed from physical domain to computational domain. |
| Keywords: | body fitted coordinate body fitted grid transportation equation equation transformation |
