Hello,

I have a little issue when I try to refine my mesh in an overset mesh simulation:

My simulation is halfway through and my overset mesh is fine and I do not want to change it. However, my moving body is now entering a section of the background mesh that I did not make fine enough in the first place so I need to refine the mesh there in order to continue the simulation without it crashing.

My problem is that every time I add a volume control and refine my background mesh, the overset mesh (moving body) is going back to its original position after remeshing...

Is there a way to refine my background mesh without affecting anything (so my moving body does not go back to its initial position) ?

thanks!
