Hello I am trying mesh a .geo filecommand line. I have added following line in the script to create 3D mesh  ( 2D meshing algorithm Automatic, 3D meshing algorithm Frontal, and Element size factor 0.02)

Mesh.Algorithm = 2;
Mesh.Algorithm3D = 4;
Mesh.CharacteristicLengthFactor = 0.02;
Mesh 3;
Save "SNF_02_cmd.msh";

When I check the mesh file in GUI I do not see existence of 3D mesh. I also confirmed in by importing into OpenFoam and Openfoam also does not find any volume mesh. But the log file clearly says
Info    : Success !
Info    : 238335 points, 1157220 elements
Info    : Done meshing 3D (Wall 1233.26s, CPU 1222.82s)

Why I am not seeing and 3D mesh in the mesh file? The log file is attached.
