Hello! I have been using snappyHexMesh for 2D flow around cylinders, which have worked fine. It have begun to crash (without any sudden changes i remember). It is a 3D mesh, which im afterwards is scalling to a 2D mesh. The snappyMesh is still working on a 2D, so i dont get where this error comes from? I get this error:

Scaling iteration 0

    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.

Number of normal edges: 1893928 number of points: 2259712
