Valid versions: 
1 Short description
Generates a mesh from a blockMeshDict. Upward compatible with blockMesh
2 Usage
The usage is similar to blockMesh. The syntax of the dictionaries is the same except for one exception: in a block specification, if there is a word between the vertex numbers and the number of cells, then the block is added to the cell set with that name.
For instance in the example from the UserGuide 2.1.6 the original blocks section
blocks
(
hex (0 1 4 3 9 10 13 12) (10 10 1) simpleGrading (2 2 1)
hex (1 2 5 4 10 11 14 13) (10 10 1) simpleGrading (0.5 2 1)
hex (3 4 7 6 12 13 16 15) (10 10 1) simpleGrading (2 0.5 1)
hex (4 5 8 7 13 14 17 16) (10 10 1) simpleGrading (0.5 0.5 1)
);
can be changed to
blocks
(
hex (0 1 4 3 9 10 13 12) set1 (10 10 1) simpleGrading (2 2 1)
hex (1 2 5 4 10 11 14 13) set2 (10 10 1) simpleGrading (0.5 2 1)
hex (3 4 7 6 12 13 16 15) (10 10 1) simpleGrading (2 0.5 1)
hex (4 5 8 7 13 14 17 16) set1 (10 10 1) simpleGrading (0.5 0.5 1)
);
This generates two cell sets:
- set1
- consists of the first and the fourth block
- set2
- the second block
If the switch --writeZones is used then no cellSets but cellZones are written.
If no cell-sets are found the utility behaves exactely like original blockMesh.
3 Technical
To work around a typo in OpenFOAM 1.2 a dummy faceZone of size 0 is generated and written.
4 Download
The tar file with the sources Basically this is the original blockMesh utility with some minor modifications.
5 History
This utility was discussed in this thread on the Message Board.
