Merging overset with Isoadvector (overInterDyMFoam and interIsoFoam)

Hi,
I'm trying to merge overInterDyMFoam with interIsoFoam to have overset functionality while reducing numerical ventilation (smearing) in naval simulations (VoF). I've compiled the attached overset solver using isoadvector instead of MULES, but when I run it I get air bubbles around the hull (picture attached) and the simulation crashes. Any idea on what I'm doing wrong? Thanks! Juan |

Hello,
Why the overset approach is required in your simulation ? If the motion is limited, first, I would go with the standard mesh deformation method, MULES, and use the interfaceCompression boundary condition. Paulin |

Hi Paulin,
Thanks for your reply! I'm using morphing mesh with isoadvector and it works fine, but also overset meshes to simulate wider movements and manouvers. I directly thought about trying isoadvector with overset mesh, but it hasn't worked out, at least yet The interfaceCompression BC seems to me like less "real" but I'll give it a go and check the results. Thanks! Juan |

ok.
Let me know if the interfaceCompression BC improves your results. Paulin |

Have you been able to merge overInterDyMFoam with isoInterFoam? Best regards, Berin |

I think the challenge here is how to correctly transfer the information (orientation and position within a cell) of the indicator function between the grids.

Hi juandeigo,
I've been doing this recently. Have you been able to merge overInterDyMFoam with InterIsoFoam? or any progress? Best regards, Souliam |

Hi Souliam,
Not yet. I got a tip that the key is mass conservation, but I have to find the time to try again. What about you? Any success? Juan |

Em... Before using interIsoFoam to modify geometricVoF, there is no problem. Then, trying to merge overinterdymfoam had fatal problems. It seems that there is no data exchange between background and overset (fig1). Also, my solver doesn't show the solve p-rgh prompt(fig2), I僧 trying to check or modify. Finally, have you adjusted the CorrectPhi.H file properly? fig: https://www.jianguoyun.com/p/DRUY1FMQzZLaChjo_cgEIAA https://www.jianguoyun.com/p/DXvZn88QzZLaChjw_cgEIAA Souliam |

Are you guys still paying attention to the coupling of these two solvers?I would be grateful if you could provide me with some ideas or insights.

I have just seen that a paper regarding the overset mesh combined with isoadvector has been published. https://www.sciencedirect.com/scienc...2980182301853X I am not sure if the code is available on GitHub or something like that. I think that the paper's author had some discussion about the implementation at the forum here: IsoAdvector: A new interface advection scheme for interFoam type calculations Best regards, Berin |
