I currently run a moving mesh case with multiple meshes, i.e. I run simulation A from time 0 to time t_A, then I map the results from simulation A, t_A onto a new mesh, same geometry, but different number of cells, and run the simulation B from time t_A until t_B, then I again map onto a new mesh and so on:
Code:
Simulation A, mesh A runs from t_0 to t_A Simulation B, mesh B maps results Simulation A to mesh B (time t_A) runs from t_A to t_B Simulation C, mesh C . . . The reason for this procedure is that I have high deformations of my mesh, and I could not run the whole simulation using just one mesh. Does anybody know if there is a possibility of doing this mesh exchange inside a solver? I guess I would need a topology changer? Has anybody done such a project and could be so friendly and share his insight? Thanks! |

I think, you can use the mapFields option to map the results from one result/mesh to a different mesh. Please check the link here which shows how to map one results to a new mesh setup. I hope, this helps. Regards, Jalvathi |

Hi!
Thank you for your reply, but I already use mapFields in my workflow. However, this procedure takes a lot of time compared to the actual CFD solver part, so I thought that putting the mesh-to-mesh part inside the actual CFD solver would speed things up. Thanks. |
