Error reading Gmsh mesh in FreeFem++

Hi !
I have an error reading a Gmesh mesh in Freefem++
#FreeFem++ script:

load “gmsh”
mesh Th = gmshload(“mesh.msh”);

#FreeFem++ output:
Element of type 5 is not considered in Freefem++

#Gmsh .geo script:

Point(1)={0,0,0,0.1};
Point(2)={1,0,0,0.1};
Point(3)={1,8,0,0.1};
Point(4)={0,8,0,0.1};

Line(1)={1,2};
Line(2)={2,3};
Line(3)={3,4};
Line(4)={4,1};

Curve Loop(1) ={1,2,3,4};

Surface(1) = {1};

Rotate {{0, 0, 1}, {0,0,0}, -Pi/3} {
Surface{1};
}
Mesh 2;

Element of type 5 is not considered in Freefem++ is 8-node hexahedron
and no hexahedron in freefem.

Thanks Frédéric !! It’s possible make a finite volume method on Freefem++ ??

Yes but to day is tricky.
