[ICEM] Yet another opinion on a blocking

diamondx · January 30, 2013, 14:47

Dear friends,

I have this geometry, project file is here https://dl.dropbox.com/u/35161486/He...%20quarter.zip

here are some screenshot of the geometry and the blocking :

I spent a lot of times trying to improve the quality, ended up finally wondering if the blocking was good enough. Can you help me improve the quality ? i now it can be one of the hardest task ! Please feel free to suggest any other strategy.

Here again, i decided to mesh one quarter, i will mirror the mesh later to get the full mesh.
i find it easier this way as i have to deal with less holes...

Thanks a lot

good approach. Simon usually recommend this way of working in ICEM

You see that left bottom small circle, too much elements are there, and i can't do anything about because of the parallel edges. this why i asked about the refinement in the other thread, i'm planing to use a refinement of 1/2 there...

did you try multizone meshing of R14.5? I guess it is awesome to try.

I don't have version 14.5 yet...

May be using some other topology resolves this problem...
