<p class="MsoNormal">Well, I was able to generate a volumetric mesh from a .stl file. However, the resulting .msh is quite large (90MB). Since I would like to do some further FE analysis, I would like to reduce the size of the .msh file which means the size
of the 3D mesh elements should be increased. Is there any command which specified the size of a mesh element? I have tried Mesh.CharacteristicLengthMin, but it seems not work in my case. Is there any examples for this scenario? Or any other commands?<o:p></o:p></p>

<p class="MsoNormal">And I also tried to use the command in the tutorial t13.geo. But my gmsh.exe crashed while executing CreateTopology.
