This question make me crazy!!!!!
 

Hello everyone!
I want to creat structure mesh in this model (like picture 1),so fitst I divide the block like picture 2, noting that I create two parts (name "suction side" and "pressure side") in the blade, But when I associate edges to the blade curves(like picture 3), the two parts(suction side and pressure side ) are the same color, It means these two part have been marged. So when I put into fluent, just a boundary in the blade, and I need to analysis the blade's suction side and pressure side. How can I do for it?:confused::confused::confused::(:(:(
I hope someone can help me !

Hello Liu,

when you assosiate an edge to two curves these curves will be grouped together prior to the real association. To prevent this, you'll probably need an additional cut dividing the two halfs. So that no single edge is associated to both sides.

With regards,
Sebastian

Thank you for you reply! I am also realize this problem, but I dont know how to aviod the single edge not associted to both sides, do you have any ideas?
Thanks in advance!

"To prevent this, you'll probably need an additional cut dividing the two halfs."

with other words: split the edge where one of curves ends. So you can prevent "overlapping".

Thanks a lot, I will try to make lt!
