hello, I am new here and have a problem when using snappyHexMesh to generate mesh.
the terminal shows ''Point (1.93 3.731 1.243) is not inside the mesh or on a face or edge. Bounding box of the mesh0 0 1.05) (50 50 1.7).'' however, while I change the locationInMesh many times, this problem still exists. Any help is appreciated !!! |

The solutions which is helped to me...
When you define the background mesh with blockMeshDict you need to change the definition in such a way that first four points have Xmin coordinate and other four points have Xmax coordinate: My working example: vertices ( (-15 55 -140) (-15 105 -140) (-15 105 -90) (-15 55 -90) (35 55 -140) (35 105 -140) (35 105 -90) (35 55 -90) ); blocks ( hex (0 1 2 3 4 5 6 7) (20 20 20) simpleGrading (1 1 1) ); As you see we start from (Xmin, Ymin, Zmin), then move to (Xmin, Ymax, Zmin), then to (Xmin, Ymax, Zmax) the to (Xmin, Ymin, Zmax) This steps repeat for Xmax plane. I think that will work for your case. Try this algorithm ) |

Hi Eric,
I am not sure if you found a solution to your problem. In case you didnt you can try the following : Delete the blockMesh related files and regenerate the block mesh I am not sure if your blockfile definition is correct. The definition needs to be in cyclic form : xmin ymin zmin xmax ymin zmin xmax ymax zmin xmin ymax zmin xmin ymin zmax xmax ymin zmax xmax ymax zmax xmin ymax zmax |
