[HELP]import/modify hexa mesh
 

Hello,

I am recruit in ICEM 14 use. I was importing a mesh from Fluent document (.msh) and adding up a little cube surface geometry/mesh in a big volume mesh part, without any further operation like merge, blocking etc. Fluent can't recognize this little piece of mesh when I re-export back the whole new one into it.

can't ICEM satisfy what I want to do by simple operation? if not, should I remesh all the parts?

Thank you in advance.
