blockMesh and surface mesh
 
I have a surface mesh, or rather grid points on a curved surface. Now I want to build a grid in blockMesh at the same exact locations I have. Is there any way to specify each and every grid point I want on a surface and tell blockMesh to construct a grid based on those points?

Its like following the bottom to top approach. I have surface mesh and I need to construct a volume mesh in blockMesh from the available surface mesh.

I think you need to use snappyHexMesh. Basically, you build a cube in blockMesh around your surface with the surface slicing through the cube. Then, you use snappyHexMesh to generate a mesh that conforms to the surface and meshes the volume from your surface to the top of the cube. The motorBike tutorial is a good model to follow. I don't think you can mesh an irregular surface in blockMesh, but snappy does it quite well.
