Blocking of diffuser augumented wind turbine
 

can someone help me with the blocking of this geometry ( wind turbine enclosed in a shroud/duct ) i am new to icem and i want to create periodic mesh of this geometry so i used 120 degree (1/3 rd ) portion of geometry and started blocking but i am confused because it seems to be complex and is this the right way to use 1/3 rd of geometry and then do apply periodic boundary conditions. Please check my geometry file, dropbox link given in description for tin file and my prj file of icem:

hi zeeshu, did you solve the problem already?
