[Gmsh] Info on tetrahedra

[David Colignon]

Hi,

If I use your example below in gmsh and I mesh it in 3D, I obtain only tetrahedra, so I don't understand your problem...

Point(1) = {0,0,0,0.1};
Point(2) = {1,0,0,0.1};
Point(3) = {1,1,0,0.1};
Point(4) = {0,1,0,0.1};
Line(1) = {1,2};
Line(2) = {2,3};
Line(3) = {3,4};
Line(4) = {4,1};
Line Loop(5) = {1,2,3,4};
Plane Surface(6) = {5};
Extrude {0,0,0.45} { Surface{6}; }
Physical Surface(101) = {6,19,27,28,15,23};
Physical Volume(100) = {1};

Cheers,

Dave
