1 Short description

A patch to the blockMesh tool to enable double graded meshes, that is meshes which have a minimum or maximum cell spacing in the middle of an edge.

2 Usage

The utility works the same way as the standard blockMesh tool, but accepts negative grading coefficients in the blockMeshDict file.

For example, simpleGrading (1 -2 1) in blockMeshDict means the created mesh has cells two times larger in the center than those at the side.

The executable is called by this command:

blockMeshDG

Source of example and original code: blockMesh with double grading
