 June 23, 2016, 02:59 perforated circular cylindrical pipe #1 New Member   Ankit Gautam Join Date: May 2016 Posts: 4 Rep Power: 9 What would be the best strategy for blocking the geometry attached in ICEM CFD? The geometry is a perforated cylinder with axial inlet and exit through radial holes and axial top. The geometry is surrounded with the pool of same fluid that is entering the cylinder. 60 degree axial symmetry exists in the geometry. Thanks in advance.

Now go block it !! Share geometry if you want assistance __________________ Regards, New to ICEM CFD, try this document --> https://goo.gl/KAOIwm Ali

I have tried several strategies but the problem arises when I create part separately for the blocks from fluid domain that contains the cylindrical geometry inside wall (solid) region. As soon as I do that the association changes and my mesh distorts. I have already posted the association problem in http://www.cfd-online.com/Forums/ans...g-problem.html that I faced and you were the one who replied (Thanks for that too). Attaching the .step file of my geometry. Thanks! computational domain small.zip

I managed to start the blocking and block on hole. it's up to you to finish it. by blocking the other holes, and adjusting the vertices, association face to surfaces if needed...
