<pre wrap="">Hello
I am using gmsh to mesh a polyhedron .geo file using command line (non-interactive mode). I would like to know how to control the mesh element (tetrahedron) size. For my study, I want to find the effect of mesh size, so I would like to know if it's possible to have meshes between the original mesh and the refined mesh, and how.</pre>
