Hello guys.

Can somebody help me with this meshing thing? I`m stuck and I can`t move forward. Thank you in advance for your reply.

Regards,
Eizo

The same as in the example above.

I got question, when I look from the inlet; i.e. right-hand side of the picture, there are only 4 blocks. The edges of the fins are chamfered, so If I would like to make blocking like you've showed me, I need to make 7 blocks? Is it the right thinking?

I do not understand what you mean. Why only 4 blocks when you look from the inlet? May be 6.

@Ralen : Very creative blocking topology.

Eizo · June 11, 2012, 04:11

What I want to say is that there are fillets at the edge of the fin. You split the inlet face into 4 blocks. My question is how you assign those blocking lines into the fin edges?

Far · June 11, 2012, 05:36

I am not sure, but I try to explain what Ralen did.

1. He made O-grid around the fin (select the faces on the two sides of far field parallel to fin)
2. and then inside the fin.
3. After that he assigned material to solid for interior of fin (you can see the edges turn to black from blue).
4. collapse the fin block and use edit edge to snap the edge to fin curve.
5. Make some necessary associations.
6. You are done

Thank you for your explanation Far. Recently I was on holiday, so now I`ll try to do the meshing as you explained. Hope everything will work.

P.S. Did you assign material for the fins after blocking, or it doesn`t matter when you do this step?

Best regards,
Eizo

wow

realyy you are gooood and specialy man

if you create a move drom your work (for mesh) will be perfect.
