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.

e.g. simpleGrading (1 -2 1) in blockMeshDict, means the mesh in central is 2 times larger than those in side.

The executable is called by the command "blockMeshDG".

Source of example and original code: blockMesh with double grading
