 July 4, 2013, 06:27 Avoiding repetition (how to divide the main block to small ones) #1 New Member   Mfm Join Date: Jun 2013 Posts: 18 Rep Power: 6 I am trying to mesh Tube bank using ICEM. After drawing the geometry I wantted to o-grid mesh each cylinders .there are like 130 cylinders (there is no way to take a portion coz the geometry isnt semmetric).The problem is I have to manually divide the main block and then apply the o-grid technique to each cylinder (just like in this video http://www.youtube.com/watch?v=T2Dxa0OZf58). I THINK EXPERTS WOULD NEVER GO THROGHT Rrepetition PROCCESS LIKE THAT).Any cluse to handle this problem.Is there command that divide the main block into small ones based on the curves (cylinders) that are inside the main block. Thanks in Advance for your help. Last edited by meshoxx; July 4, 2013 at 17:31.

I drew one horizontal row then I transformed it vertically.
