Contrib blockMeshDG
From OpenFOAMWiki
Contents
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
