dear friends:
I need to add the 4 sides and a bottom to this obj terrain file. So we can import it into the snappyMesh.

You don't need the borders as STL to use snappy. Just make sure that blockMesh cut the terrain and that the rectangular are of blockMesh is not greater than your terrain stl

Thanks, but the stl file now is only a surface. it must be and enclosed volume as i know.

No I already made a mesh within a terrain surface like yours. Check the turbine siting tutorial https://develop.openfoam.com/Develop.../turbineSiting
