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 sam 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 no cell-sets are found the utility behaves exactely like original blockMesh.

3 Download

The tar file with the sources Basically this is the original blockMesh utility with some minor modifications.

4 History
