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 |

Look into sweep meshing. One element in sweep direction

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

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? |
