SnappyHexmesh error
 

Hi, foamers:

Firstly, I used SnappyHexmeshDict to refine mesh and remove a small cylinder. And then I used toposet to define some faces. Allrun is:
#!/bin/sh
# Source tutorial run functions
. $WM_PROJECT_DIR/bin/tools/RunFunctions
# Set application name
application=`getApplication`
rm -rf constant/polyMesh/*.gz
rm -rf constant/polyMesh/sets
rm -rf 0/polyMesh
rm -rf 0/*.gz
rm -f log.blockMesh
runApplication blockMesh
rm -f log.snappyHexMesh
runApplication snappyHexMesh -overwrite
rm -f log.topoSet
runApplication topoSet
rm -f log.createPatch
runApplication createPatch -overwrite


when I decompose, the errors occured as follows


........
Processor 31
Number of cells = 46723
Number of faces shared with processor 27 = 657
Number of faces shared with processor 29 = 1870
Number of faces shared with processor 30 = 1855
Number of processor patches = 3
Number of processor faces = 4382
Number of boundary faces = 4368
Number of processor faces = 86026
Max number of cells = 46723 (0.0131109% above average 46716.9)
Max number of processor patches = 6 (11.6279% above average 5.375)
Max number of faces between processors = 5875 (9.26929% above average 5376.62)
Time = 0

would you like to tell me what is the problem? How to recitfy it?
Attached are the files including blockmeshdict, toposetdict, createPatchdict, snappyhexdict, Allrun.

Thanks

I might be wrong but I believe is this due to the presence of an old mesh with a different number of cells. Try to delete the old mesh (not the input files as blockMeshDict etc.; make a backup first!!!) and start your meshing script again.

Hi, Cutter, Thank you.
But I have done this many time. Cleaned all files every time and started again.
This problem is still there.

Greetings to all!

@ yiwang25: Run this command:
It will remove the files "ccx", "ccy" and "ccz", which are created by snappyHexMesh, if I'm not mistaken, and are useless unless you want to do some debugging.

Best regards,
Bruno
