[Gmsh] Question on GMSH

[Timothée SCHLATTER]

hello,
I'm working on the 1.56 version of GMSH and I want to do a mesh in 2D.
I would like to know if it is possible to define a non plane surface 
like in this example :



Point(1)={1,3,0,1};
Point(2)={1,3,2,1};
Point(3)={3,1,2,1};
Point(4)={3,1,0,1};
Point(5)={6,4,0,1};
Point(6)={6,4,2,1};
Point(7)={9,2,2,1};
Point(8)={9,2,0,1};

Line(1)={1,2};
Line(2)={2,3};

Line(4)={4,1};
Line(5)={4,5};

Line(7)={6,3};
Line(8)={6,7};
Line(9)={7,8};
Line(10)={8,5};




Line Loop(1)={1,2,-7,8,9,10,-5,4};

I want to mesh this surface with respect of the relief defined.

Best regards.
