Hello everybody.
I want to use overset mesh for fluid structure interaction like those in the third figure of the attached picture below. I think Official OF1706 or OF1712 do not have fluid structure interaction facilities like fsiFoam available for foam-extend 3.2 or 4.0. Thus, I think it is better to use overset mesh with foam-extend. I asked Prof. Hrvoje Jasak for overset code in Foam-Extend. He kindly provided me with Foam-Extend 4.1 code (It is not officially released yet. But you can email to Prof. Jasak if you want to try). But as far as I understand, this code focuses on solid body motion rather than deformed patches. For me, I need to deform the overset mesh while the background mesh is not changed. In other words, the whole overset domain (I am not sure I should use the word 'domain') should deform properly so that I can maintain mesh quality. I guess I need to write a mesh motion solver for overset mesh region. Any help will be greatly appreciated. |

Hello Thaw,
Did you figure out how to deform the overset body? In addtion, do you know how to deform the background mesh with overset? I try to use overset mesh in a deforming background mesh. I noticed dynamicOversetFvMesh is derived from dynamicMotionSolverFvMesh which means overset should be able to coupled with dynamic motion solver like velocity/dispalcementLaplacian. But I do not know how to set up the dynamicMeshDict. Do I need write code to integrate overset with deforming? Thank you! Michael |

Anyone manage to get it working - overset mesh with deformation?
I wonder if it is possible, or the source code must be modified to make it work this way. |

How are you doing? I have the same problem with using flexible overset mesh on OpenFOAM, have you managed to solve this problem? Best, Tian |

Sorry, I gave up on using overset mesh.
