hi! foamers

I trying to generate pipe mesh using foamyHexMesh utility

but I cannot generate mesh.

I used tutorial file in foamyHexMeshDict of flange case.

During the generating mesh appears this warnning


Writing internalDelaunayVertices to "100"

Calculating target cell alignment and size

Merging identical points
mergeIdenticalDualVertices:
zero-length edges : 3696

mergeIdenticalDualVertices:
zero-length edges : 560

mergeIdenticalDualVertices:
zero-length edges : 0

Merged 4256 points
--> FOAM Warning :
From function Foam::conformalVoronoiMesh::buildDualFace
in file conformalVoronoiMesh/conformalVoronoiMesh.C at line 655

boundary points. Defining Delaunay edge ends: 61987 InternalSurface at0.02793222881 -0.09145699466 -0.0004) size:0.004 alignment0.9623622024 0.271769476 0.0005859776959 -0.2717695505 0.9623623584 5.001555281e-05 -0.0005503301768 -0.0002073839726 0.9999998271)" free, " (local)

is this warning related to the error ?

Thanks to all for willingness!

You'll need to post your whole case...

Have you considered using the 2D version and extruding the mesh?
