cell connection by vertex

Hello Foamers,

First of all I would like to thanks some Foamers whose suggestions and ideas has has helped me greatly in my work. I would like to thank Mark Olesen, Martin and Fabien Robaux.

I am in trouble again. I want to access the neighbors of the cell from the vertex list.
Since meshcellcells() gives neighbor of the cell connected through faces. I want something which can directly give me neighbor of the cell connected through vertex. So In 2D I could get all 9 point stencil. I guess it is a very common objective so there must be some way to do it in OpenFoam.

Hi,

If I got it right you need node to cell connectivity.
For this you can use mesh.pointCells().
See my blog for details.
