Hi All
I am trying to simulate air-water flow inside a pipe using interFOAM. Does interFOAM comes automatically with dynamic mesh? or do I have to implement it? I am using the angleduct tut solver. Thanks. |

Hello,
Yes, interFoam includes dynamic mesh capabilities. Code:
Solver for two incompressible, isothermal immiscible fluids using VOF phase-fraction based interface capturing. With optional mesh motion and mesh topology changes including adaptive re-meshing. You should be able to find few examples in the interFoam tutorials (look for tutorials using a dynamicMeshDict file) Regards, Yann |

Hi Yann Hi Yann, Thanks. I am just wondering whether I would require dynamic mesh for my problem. It is water falling from a height and flowing inside a 3d pipe with a vertical height. The air-water interface seems to be strange near the fall but becomes smooth as it flows rightwards. Attached is the picture. Also if I want to implement dyn mesh for my problem, are there any good learning materials? Thanks |

It is strange indeed but I don't know what is going on.
In ParaView, could you plot cell values rather than node values? Yann |

If you are using paraFoam you have both node and cell values by default (see screenshot)
