Hello,
i modified the DamBreak 2D tutorial, an add the third generation. The position of the alpha.phase 1 column i changed also. Here is a picture with three views at the timestep 0. ![]() https://www.imagebanana.com/s/1919/lHbZccfd.html And here at the timestep 399 (4 sec) https://www.imagebanana.com/s/1919/Qb68DaA8.html Why is the "water" collected at the edge of the x axis ? I dont changed the g file the value of the gravity is still 0 -9.81 0. Usually the water should distribute at the x axis and y axis face ? Best regards Kai |

I didn't download your setup, but I'd suggest you to check whether your case is still using empty boundary conditions for the front and back patches.

Hey guin,
thank you for your reply. Yes, both of them are empty. In Paraview they are called defaultFaces. I will try to set a wall boundary aswell and run the case again. Best regards Kai by the way: i have an offtopic question. How you find the right vertices, faces and so on for the blockMeshDict File. I can open the geometry in Paraview, but i dont find a way to display the vertices or face numbers. |

I got this message:

Hey guin, yes you are right, i changed the patches (front- and backwall) from "empty" to "wall". In the new run the water distributes "right" on the floor. But why does have the patches so much influence to the alpha1 phase ? What is different in these two simulations ? Best regards Kai

Hi Kai,
The empty type is meant to be used on 2D cases. Have a look at the documentation : https://cfd.direct/openfoam/user-guide/v7-boundaries/ Quote:
