hello pradeep

can you post your email id, i will send you the presentation on how to go about setting up the blocking.

Thank you
jeevan

Dear PSYMN
Thanks..thanks..thanks..thanks a ton, it seems to be working.

Dear PSYMN
Now there is another problem, the mesh generated through this method is looking absurd as you can see in attachments. I suppose i will have to further split blocks, as you have done in your illustration(4th blocking ).
I tried that as well (by taking different combinations of faces) but couldn't get that kind of blocking.
So i need your help a bit more..!!

There is some problem with image uploading, i will do that soon.

Thanks & Regards

Thanks to all for bearing with me...!!
I successfully created mesh in an U bend tube...
Suggestions provided by PSYMN & Jeevan were really helpful...
Thanks again..

Hello PSYMN
This is the 2-D geometry that i was trying to mesh.

PSYMN · December 24, 2010, 09:14

And how did your final mesh look?

Hi,

I followed your steps but I cannot figure out how to adjust the blocking so it can fit the U-pipe after creating the O-grid. I tried moving vertices around and associating edges to the inlet and outlet but it does not give me a uniform mesh. The mesh is very skewed. So, how do you adjust the block after creating the O-grid, which is the last step in your illustration above?

How do you perform the last step in the top-down method? I created an O-grid and deleted the center block but then cannot get a good mesh quality. I tried slicing the blocks and moving vertices around to fit my geometry but I obtain a very bad mesh quality

Hi jeevan, would you be able to send me the presentation as well? I am encountering the same problem. my email is mohamedzaki93@hotmail.com

Thank you!
