Dear All., I would need assistance with this meshing issue. Basically am creating an hexa mesh in ICEM CFD of a tapered wing with sharp trailing edge.

After premesh when I check the quality am getting angle <18deg, which means a negative volume elements there.

I tried refining the mesh size, changing the blocking approach, but nothing seems to be working at the sharp corner. Saw few youtube videos and in all the videos they haven't shown the quality and haven't exported to fluent.

I've attached few snips for better understanding, any help would be really appreciated. Thank you.

1. truncate the trailing edge.
2. convert trailing edge block into unstructured pave block.

Hello sir, thanks for the reply.
But am really not able to understand the meaning., i tried google the words,

Truncated the Trailing edge - yu meant to say reduce trailing edge so that it becomes blunt trailing edge from sharp trailing edge!??

Convert block to unstructed pave block - i didnt understand this sir. Please help me get through this.

Truncated = Blunt or square trailing edge. You can also make it round.

From edit block, there is option for convert block type

I'd go for option 2 in order to save quite some extra work.

Hello Mr. FAR and Mr. HHOS.,

I couldn't find the option to convert into pave block. neither i couldn't find anything related to it in google.

I enclosed a snip., please guide me in this.

Thanks.

use swept method. Pave is another thing and is available with multizone mesh in ICEMCFD
