Dear OpenFOAMers,

I generated a mesh of axisymetric tube using blockMesh. When checked using checkMesh, I got the following message:

***Number of edges not aligned with or perpendicular to non-empty directions: 280332
<<Writing 287066 points on non-aligned edges to set nonAlignedEdges

and checkMesh saved the noneAlignedEdges to polyMesh/sets.

Can someone explain what it means?

When plotting with paraFoam, the mesh looked fine though.

It's quite an old questions but maybe someone has a look here when facing this problem.
I found something about it on the OpenFOAM Wiki website. Paragraph 9 is the important one.

I also got those issues, but after propertly naming all my patches it disappeared, like ramhari said.

This is probably too late for replying this question. But I hope it will help the others, who will have the same problem in the future. I had the same problem. And I solved the problem by renaming all the points labels.
