Hi all,

From the attachment, I face some problem in meshing the top part of the channel. I am interested in meshing 2D, thus I would like to mesh the top part of the channel as a single rectangular cell instead of a rectangular cell containing two triangles, as shown from the attachment. Any help on this is much appreciated. Thanks and looking forward to your response.

Cheers
Francis

Thanks for the reply. I am also interested to apply inflation near the wall. The sweep method seems not compatible with inflation method, may I know is there any alternative way to do it?

Right click on the sweep method and choose "inflate this method".
When sweeping you inflate a face from an edge, then sweep that face through the body. This is not the same as other methods where you inflate a body by selecting the wall surfaces.

Hi, could you explain why we need block after drawing the geometry, before the mesh? Thanks

Blocking means you are subdividing your volume into smaller blocks which can be mapped mesh.

Hello,

I met a problem after I finish my mesh. After I pre-mesh it, and I 'loading from block', in the command window, it says
'Unloaded unstructured domain
--- Unloading existing mesh
Loading domain "hex.uns" ...
domain has 0 nodes'

Does anyone know why, and where I have made the mistake? I am looking forward to your reply. Thank you.

well, I am sorry for that, I am new here, but I know how to open new thread now.

And thanks for your answer,it has nodes now, but hexas=0, and I cannot import the mesh into FLUENT, and in the fluent command, it says 'Error: Null Domain Pointer'.
Do you know why?

It is 2d case? Did you choose 2d option while exporting mesh? are you opening this mesh in 2d version of Fluent?
