Structured or unstructured meshing of a STL file (surface)

I have a surface in stl format and I want to use structured mesh for it and later I want to export it to OpenFOAM. So, I want to have a cubic which the bottom surface is my stl file and then I can apply OpenFOAM boundary conditions to it.
I import the stl file, create the connectors and define the space averaging and do the unstructured mesh on the surface but I cannot make that cubic (like in OpenFOAM). How should I do that? I used extrusion but the result was awful. In addition, I want to have structured mesh, so you think it is possible? when I use the structured option, no domain is created but with unstructured at least the surface is meshed good. what should I do?

The figures are not understandable look like some grass fields.
Try to import STL file as database then mesh on that.

Here is a brief article about someone else doing what I think you are trying to do: http://www.pointwise.com/theconnecto...Analysis.shtml
To make a structured grid on this surface you will need 4 edge curves, and opposite edges need to have the same number of grid points on them. If the outer boundary of your STL geometry does not have a roughly quadrilateral shape, you may have to manually break up and/or join the connectors Pointwise automatically creates to get 4 connectors and manually redimension them to have the same number of grid points on opposite edges.
Then select all 4 connectors and hit the "Assemble Domains" toolbar button to make a structured domain. You may have to project it onto the STL geometry after it is created.
