Hello all,
Can someone enlighten me about the origin of the following message from the checkMesh utility?: This mesh has no valid solving directions. dirs = (-1 -1 -1). Please check mesh definition for empty patches. This is a 0-D mesh Overall domain bounding box (-4 -3 0) (4 3 0.5) Mesh (non-empty) directions (0 0 0) Mesh (non-empty, non-wedge) dimensions 0 ***Number of edges not aligned with or perpendicular to non-empty directions: 22126 <<Writing 11884 points on non-aligned edges to set nonAlignedEdges Has this something to do with the consistency of the axis coordinates when I define my blocks? |

TIP: When creating a mesh, frontAndBack patches cannot be set up initially as empty ones. That's the reason of this error. Initially set it up to "patch", then you can redefine it in "polyMesh/boundary" file to "empty".
Hope it solves your problem. Best, K |

Hi
I like to move my mesh's cell only by dx/2 and dy/2 and create a new mesh. Could you please help me how to change the blockmesh file to create a new mesh whose cells are moved by dx/2 and dy/2 relative to the first mesh? Thanks a lot |

While this post is really old, but in case it comes up on a google search: I think what you're looking for, for shifting a mesh, is "mergeFields".
