Automesh for tetrahedron

Hello,

here are soem short answers:

..wires, faces & tetrahedra...?
This is the normal way of mesh generation in Salome: it generates all dimensional elements (1D,2D,3D). In that sense, it is similar to GMSH too. Depending on the simulation code used afterwards, you will need (or should not) delete some kind of elements. But for Code-Aster, you should absolutely keep all elements as the extra-elements (faces for ex.) are used to define boundary conditions.

..specify length..?
To specify lengths, the most practical way is to use the Average length hypothesis in 1D instead of the \"automatic\" (and often faulty) length. If you want to specify other sizes on specific regions, you will then need to create a \"Sub-mesh\" with another set of hypothesis (for ex. average length = 0.1 instead of 0.6 in the global hypothesis).
