periodic mesh copy in ICEM
 

Hi you guys, I need to generate copies of original mesh and geometry. I use the methods described below, but none of them can be imported into fluent correctly. Only original part can load into fluent, while all the copies are lost.
method(brief description):
1) translate geometry with several copies（increment the part also）, loading mesh from block for original one, translate original mesh with copies, output....
2) translate geometry with several copies（increment the part also), translate original block with copies(and I cannot see the premesh of the copies), loading mesh from block, output...
Thanks:)
