Converting a scanned surface to a mesh
I have a scanned surface as seen in the image below. I'd like to use this in OpenFOAM. I'd like examine how fluid flows over this surface, so I think the easiest way might be to have this become the roof of a pipe segment, with the walls and floor as simple straight boundaries that are no stick.
I collected the data as a point cloud with a scanner and then meshed it using 3rd party software. I have the CAELinux Virtual Machine so I can pass it through Engrid or gmsh or some other tools. I am seeking advice about which tool or workflow would be the best to modify the surface to become part of a pipe.

By the way, the advantage of using snappyHexMesh is that you do not need to create a tube, you can use a box and made directly with blockMesh.
In addition, you might want to look into the following add-ons for Blender:

Thank you for your reply. Sorry for my delay, I was on vacation last week. I'll let the other EnGrid thread die out and continue here, since I am not using EnGrid.
I figured out to just use blockMesh and snappyHexMesh as you suggested, although I ended up figuring this out by using discretizer and the video tutorials on that website.
