Can I output SimLab FE Model to Hypermesh?

I use the SimLab to automesh the 3D triangular mesh 

and now I want to use this FE Model in optistruct

I also want to ask why I set automesh in hypermesh the element is so large

I set the  Mesh>Tetra Mesh>Volume tetra>Element Size>4, but it still large

so what can I automesh in hypermesh
