No


What is the element type generated by this

Why generate the surface mesh, save it, and reload it to embed it in a control volume ?

Just define your control volume in the same .geo file where you define your surface, and mesh all at the same time. But 
you have to be careful if the surface touch the surface of the control volume, you cannot have overlapping surfaces.
