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.

It's seems like the problem for the following thread as below. You can refer to this article to solve it:

Restart overset simulation from latest time

The test of restart I tried is that:
1. copy "time/polymesh/point" to cover "constant/polymesh/point".
2.set initial value (centreOfMass,velocity ,angularVelocity ,orientation) for "dynamicmeshdict".
Notice that, all the values mentioned above depend on the restart time.

It's work for me to solve overset 6dof case by the solver, "overInterDyMFoam".
