Generating a mesh with a MRF region using snappyHexMesh:



-- using cylinder option (primitive shape available in OF-1.6 and above) and defining it in the geometry sub-dictionary in snappyHexMeshDict

cylinder
{
type searchableCylinder;
point1 (0 0 10);
point2 (0 0 20);
radius 10;
}

Using this as a refinement surface and obtaining the cells inside as a MRF cellZone.

To generate a 2D mesh using snappyHexMesh: Its an indirect way but at times can be helpful. The following steps need to be considered:

1. Generate the snappyHexMesh with empty patches but with more than one cell between them.

2. Using the above mesh as a source extrude one of the empty patch in the normal direction with a single cell. This would result in a mesh with only two or three patches.

3. Using the autoPatch...
