What is this in snappyHexMesh ?
 

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

and then

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

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:

Correct-ing 2-D mesh motion--> FOAM Warning :
From function twoDPointCorrector::twoDPointCorrector(const polyMesh& mesh, const vector& n)

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.

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:

Any idea or comment is greatly appreciated.
