Summary0003334: renumberMesh behavior in OF7 is not consistent with the behavior in OF6.
DescriptionIf you use a non-uniform initialization (setFields, mapFields or potentialFoam) before running renumberMesh, the mesh connectivity seems to be broken.

In the attached figures you can see the results in OF7 (of7.png) and in OF6 (of6.png).

In seems that in version OF7 you need to do the non-uniform initialization after renumberMesh.

I dont know if this is the desired behavior but it wasn't like this in version 6.
Steps To ReproduceIn the attached case follow these steps:

blockMesh
rm -rf 0
cp -r 0_2D 0
setFields
renumberMesh

This will give you the wrong results.

To get the right results:

blockMesh
rm -rf 0
cp -r 0_2D 0
renumberMesh
setFields

While I would recommend that you run renumberMesh -noFields before setFields, which is more efficient, renumberMesh should renumber the fields correctly. I have traced the problem and applied a fix which I am now testing. I will push to OpenFOAM-7 and -dev if there are no problems or side-effects.

The -noFields option has the same problem.

At least on my installation.

If I use

renumberMesh -noFields
setFields

it works fine
