Dear all,
I have got a general problem with hexa-meshing of my geometry. My geometry has several bifurcations and branch-offs and I want to generate an O-grid for it. But at the moment I am not able to find the correct position of the blocks. I already got an advice how to place the blocks for my first bifurcation (thank you, Timothy!), but for any reason my mesh looks still strange, especially at the bifurcations. Furthermore, I already moved the vertices of the blocks several times, but the resulting grid always contains a lot of negative volumes and degenerated elements and smoothing doesn't help at all. I am afraid that's a problem due to my general way of how I position the blocks (normal and o-grid) and my way of meshing . Does anybody can give me an advice or maybe recommend a good tutorial for this problem (I couldn't find one which helps me dealing with this special problem)? Thanks a million in advance! Lilly |

Associate the edges to the curves.

Thank you, BrolY!
I did this for the inlet and outlets. Do you mean I should try to create further curves at the bifurcation and do the association there too? |

Yes, do the association for each bifurcation !
