Overset mesh size differences
 

Hey CFDians,
I am using OverIntDymFOAM to run a floating body tutorial. While i tried to run the simulation, I got this error as below:
" Cell:864425 at:(0.455 0.38 0.3295) zone:0 changed from hole to calculated but there is no donor"
I am not sure what this error means.

Also, it would helpful if someone could tell me how to have the Background Mesh and the OversetMesh at a matching cell refinement.

It would be much useful if anybody could advice with a solution. :)

Thank you. :)
