[mesh manipulation] Overset mesh size differences

bagya vivekanandhan · November 21, 2019, 16:40

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.

Exactly, I have met the same problem and do a lot efforts to solve it. Eventually, I have test the same case without any modification, everything is ok on the version 1912. So, I think you'd better check the overset region and background region, ensuring that sufficient overlapped meshes between the regions. Anyways, you could run the case on other versions, like version after v1912. Best wishes~
