Hello,
I don't no excactly why your sphere doesn't work.
In interactive mode,when making the volume the program doesn't detect the closed set of surfaces.
The problem maybee the angle of rotation equal to 2*PI.
Here is a working sphere:
c=0.1;
r1=1.0;
//Sphere
Point(1) = {0,0,0,lc};
Point(2) = {0,0,-r1,lc};
Point(3) = {0,-r1,0,lc};
Point(4) = {0,0,r1,lc};
Line(1) = {1,2};
Circle(2) = {2,1,3};
Circle(3) = {3,1,4};
Line(4) = {4,1};
Line Loop(4) = {3,4,1,2};
Plane Surface(5) = {4};
Extrude Surface {5, {0.0,0.0,1.0}, {0.0,0.0,0.0}, 2*Pi/3};
Extrude Surface {19, {0.0,0.0,1.0}, {0.0,0.0,0.0}, 2*Pi/3};
Extrude Surface {33, {0.0,0.0,1.0}, {0.0,0.0,0.0}, 2*Pi/3};
Surface Loop(47) = {13,18,27,32,41,46};
Volume(48) = {47};
Physical Volume(49) = {48};
