I’m doing LES of t106a cascade and I've made this mesh by ICEM CFD

Any idea to improve the mesh quality in trailing edge and leading edge ?
Here is my blocking

Any suggestion for editing my blocks ??

i would greatly appreciate it

see this post, http://www.cfd-online.com/Forums/ans...-elements.html

I would recommend that you should go for the shifted periodic for LES simulation (post # 15 in above thread).

tnx for your answer dear Far but i don't have negative volume elements. I have seen so many tutorials on youtube but non of them has the the curvature of my blade. I want to produce a H-o-H grid but i don't know blocking strategy for Ogrid.
