Hi,
I used snappyHexMesh successfully, but now it doesn't seem to work fine during snappy.
After castellated meshing I obtain:

Correct-ing 2-D mesh motion--> FOAM Warning :
From function twoDPointCorrector::twoDPointCorrector(const polyMesh& mesh, const vector& n)
in file twoDPointCorrector/twoDPointCorrector.C at line 169
The number of points in the mesh is not equal to twice the number of edges normal to the plane - this may be OK only for wedge geometries.
Please check the geometry or adjust the orthogonality tolerance.

and then

Scaling iteration 1
Moving mesh using diplacement scaling : min:0.75 max:1
Correct-ing 2-D mesh motion ...done

At the end, the result is that the snappy mesh is like the cast mesh!
Do I need to increase the toletance in snapControls?

Thanks for any help

Andrea

stupid error! I had an empty patch!

I got the same Error with no empty Patch, and i can find nothing about this Error on the net:

Greets, Hannes (desperately hoping for an answer, finally)

Does your mesh consist of only one cell in a specific direction? This maybe (!?) a reason why snappy thinks, it is dealing with a 2D mesh.

Dear Jens,

thanks a lot for your post. That was not the reason, but I had two empty patches. Setting them to walls solved it.

Hello all,

I get a similar message in OF-1.5-dev. My case is 2-D axisymmetric and I created the mesh with blockMesh in OF. the solver actually starts running but after 1 iteration it diverges and reports the following error:

From function twoDPointCorrector::twoDPointCorrector(const polyMesh& mesh, const vector& n)
in file twoDPointCorrector/twoDPointCorrector.C at line 175
The number of points in the mesh is not equal to twice the number of edges normal to the plane - this may be OK only for wedge geometries.
Please check the geometry or adjust the orthogonality tolerance.

Any idea or comment is greatly appreciated.
