Hello everyone, I am using overset mesh for a FSI case, and since the simulation takes a long time, I occasionally have to cancel and restart it from the latest time step. However, when I restart, the airfoil's center of mass reverts to its initial position rather than continuing from the last position before stopping. Has anyone encountered a similar issue or know of a solution? I have attached the vertical movement of the airfoil for both the uninterrupted case and the situation where the simulation was restarted.
In you fvsolution file try adding this line " correctPhi yes; " in the pimple section. Give it a try and let us know.
Dear Ahmed Raafat, Thank you for your response. I tried using 'correctPhi yes;' but the moving mesh still returns to its original location and restarts the simulation from there. I came across this post "https://www.cfd-online.com/Forums/openfoam-solving/253014-restart-overset-simulation-latest-time.html" on CFD-Online: Restarting an Overset Simulation from the Latest Time, which seems to provide the only solution to this issue. However, it involves multiple steps to properly restart the Overset mesh.
Hey, did you find a way to restart your simulation in a easy way ?
