Element size definition of Tetrahedral mesh
 

Hello all,

I have done a simulation in structured mesh by icem, and now I am switching to see the effect of unstructured mesh (tetrahedral) on my results.
I needed 1mm resolution for my structured mesh, but I don't know how to interpret this in the case of tetrahedral since it is not clear for me what the definition of element size in tetrahedral case in workbench meshing is.

I would really appreciate it if anyone can help me with the deifinition,

With best regards
