<br>Tim, what do you suggest? In a way, it should be easier to update 4.6.2. But I don't want to merge to the master after that, there are too many changes. This patch should work out of the box for 4.6.2, after I build cgns.<br>

Hi Carlos,<br>
It looks like it is a bug in 4.6.2.<br>
I don't know if it will be fixed, there are some important changes in ghosting in current version.<br>
So for Version4.6 branch, the model with 17 quads works fine if you don't do ghosting:<br>

That code is pretty complicated, and I am not sure if we will backport changes to Version4.6 branch.<br>
