Problem while modyfing pitzDaily mesh
Hi everyone! I encountered a strange mesh error while I tried to modify the 2D mesh of pitzDaily case. The purpose was to slightly change the geometry and see how the flow behaves and changes (to enrich the presentation for lecture 17). I wanted to practice snappyHexMesh and confront the result with blockMesh. Unfortunately, when I create the mesh, the refinement at the edge in the figure below produced the following error:
***Number of edges not aligned with or perpendicular to non-empty directions: 17
<<Writing 15 points on non-aligned edges to set nonAlignedEdges
Do you have any idea of the nature of this error and why does it appear?
I know that I could solve by simply using blockMesh, but I expected to have similar results.

Hi,
To make 2D mesh you points in one side should be identical since you should extend in the 3rd direction to obtain 3D mesh. However, since you used snappyHexMesh I think that your side points are not identical. Additionally, I never tried 2D mesh with snappy before since snappy should use always for complex 3D geometries.
For your info.
