I see the solid cantilever beam with 1000 N in the -X direction. I don't understand what you are trying to accomplish with the surface. Do you want it to exactly match the curvature of the beam? What for?
Did you consider using a line to represent the beam and mesh that line with beam elements. Then you would have a row of nodes down the centerline of the beam. You can export the directional deformation of those nodes and put the values in a spreadsheet. You can add the deformation to the node coordinates to construct the deformed shape in CAD.
