Hi all

I am trying to create an overset mesh for a problem of cylinder falling into water. I did the mesh and when i initialize i get the error "found inactive faces in region background.Could be due to too coarse or fine. I have made sure that the region of overlap has the same mesh size and has more than 4-5 cells.

Can anyone please help me out with the error?

The cells in the outer of the overset mesh is of 0.1 m and that in the background symmetry plane is of 0.125 m. I have attached the mesh and status diagram..

Please tell me what i should check. I have tried to change the sizes and check but still i get the same error.

Regards
Arun
