[Gmsh] Problens in a second order 3D mesh.

[David Colignon]

Hi Antonio,

it seems there are some problems in your geometry:

a) Line(2) = {2, 2};

b)
Surface Loop(60) = {51, 12, 47, 56, 55, 21};
Volume(61) = {60};
Surface Loop(62) = {21, 33, 10, 25, 29, 34};
Volume(63) = {62};
Physical Volume(64)={61,63};

The extrude command "Extrude {0, 0, -1} {Surface{10, 12};}" automagically creates the volumes n°1 and 2 (To know the
volume numbers, check Tools->Visibility

see aaaa.geo

Cheers,

Dave
