Hi,

Here you have an example of blockMeshDict file that uses macro substitution to generate a simple cylindrical geometry based on a few user input values.

Well, actually it only generates 1/4th of the cylinder, which allows to keep the file reasonably small. You can make use of mirrorMesh to generate the complete cylinder, e.g.:

blockMesh
cp system/mirrorMeshDict_xAxis system/mirrorMeshDict
mirrorMesh -overwrite
cp system/mirrorMeshDict_yAxis system/mirrorMeshDict
mirrorMesh -overwrite

Hope someone finds it useful.
