cf. my previous mail: only transfinite meshes are saved in .p3d files:

Point(1) = {0, 0, 0};
Point(2) = {4, 0, 0};
Point(3) = {4, 4, 0};
Point(4) = {0, 4, 0};
Line(1) = {4, 3};
Line(2) = {3, 2};
Line(3) = {2, 1};
Line(4) = {1, 4};
Line Loop(6) = {1, 2, 3, 4};
Plane Surface(6) = {6};
Extrude {0,0,20} { Surface{6}; }
Transfinite Line "*" = 11 Using Progression 1;
Transfinite Surface "*";
Recombine Surface "*";
Transfinite Volume{1};
