Hello foamers.
This is my first entry at this forum. Sorry for any inconvenience. I need to simulate a free falling object in a medium, like a rock in a water I could not find any dynamic mesh solver for this particular problem. While the object is moving to bottom, it cause a shrinkage on the meshes under it and the simulation crashes eventually. I used sixDoFRigidBodyMotion. It can simulate the coupled motion of the object but does not remesh the domain or change the topology. Which dynamic mesh solvers or which meshing strategy should I use? I would be very happy If you can share your comments with me. |

Hello,
Check the sphereDrop tutorial, it uses layer addition/removal technique with a sixDoFRigidBodyDisplacement boundary condition to simulate a falling sphere. Or as CFD_10 suggested, go for overset. Cheers, Yann |

Hello,
Please note this tutorial is only available in the OpenCFD branch. https://develop.openfoam.com/Develop...nar/sphereDrop If you have an OpenFOAM version from this branch already installed, then you already have the tutorial in your installation directory: $FOAM_TUTORIALS/multiphase/compressibleInterDyMFoam/laminar/sphereDrop Cheers, Yann |
