[Nek5000-users] How to achieve the exo format mesh with HEX20 type?

[nek5000-users at lists.mcs.anl.gov]

Dear Neks,
      I have seen that the tools exo2nek is proposed for mesh format conversion but I am quite wondering how I can get the .exo format mesh from ICEM. Should I directly output the unstructured mesh with the solver selected as EXODUS-II and put the .exo mesh into use for exo2nek? How can I ensure the .exo format is comprised of HEX20 meshes? 
     Thank you so much for your comments!
