My reading of the question is that he's fixing the four sides of a
rectangular section of membrane at a certain constant displacement (on
three sides) and at F(x) (the fourth side), and needs a minimal-energy
surface which satisfies those boundary conditions in the static case.
If that's the case, and he can solve the problem analytically or
numerically, he just needs a Plot3D statement with the arguments as
(say) the Cartesian coordinates of the membrane projected on the x-y plane.
Of course, I may be way off there.
