hi dear all
i run a spillway model, i want obtain velocity quantities exactly in 0.6 of the free surface, because in experimental data also rusult obtained in this distance(0.6 of the free surface), how do this? i am familiar to define isosurface, iso clip, boundary intersection in poly line, but None this methods, solve not my problem. thanks |

Create "User Surface" 6in from surface you want results from. Plot/Extract results on/from User Surface

dear singer1812
This distance (0.6) must be entered in one of tab in user surface? unfortunately dont understand your order, i should velocity in 0.6 m of the free surface, and other problem is find free surface in model? are exist exact way for find it? thanks |

You can get the free surface by a isosurface of volume fraction = 0.5. Then do the user surface offset from this surface as Edmund says.
