Summary0001486: renumberMesh mixes up wedge patches
DescriptionAfter running renumberMesh on a mesh of wedge with blockMesh, warning messages similar to this appear for every cell.

--> FOAM Warning :
    From function wedgePolyPatch::calcGeometry(PstreamBuffers&)
    in file meshes/polyMesh/polyPatches/constraint/wedge/wedgePolyPatch.C at line 72
    Wedge patch 'symPlanePosX' is not planar.
At local face at (0.00010079841 0.00018913757 -0.000748503) the normal (0.99905004 0.043577725 0) differs from the average normal (0.99905003 0.043577952 6.0446643e-21) by 5.1497575e-14

However, the checkMesh -constant returns that everything is OK.
Running just blockMesh, without subsequent renumberMesh, the error messages to not appear and checkMesh -constant still returns that everything is OK.
Steps To Reproduce* Create a mesh of a wedge geometry with blockMesh
* Run renumberMesh -constant
* Run any application such as checkMesh -constant (the error appear when reading in the mesh, therefore even a solver could be run)
TagsNo tags attached.

The renumbering is ok, it is just that the planarity check is quite strict. Are you running with binary writing?

I am running on ASCII writing. Should I be running binary in order to avoid this issue?

The issue was not there in 2.3 and only came after updating to 2.3.1

In general you want to run in binary if you're doing any kind of mesh manipulation. Or increase the writePrecision.

Running in binary or increasing the writePrecision from 8 to 10 solves the problem.
