Hello all,
Below there are two pictures are the mesh from the paper, another is my meshing. At first, i thought i doing good in meshing because is similar to the paper but got people said my meshing is terrible.

From the paper i refer, it stated that the inlet, outlet and symmetrical region are appropriately defined and subjected to sweep mesh by inflating the boundaries. Also, the inlet and outlet are subjected to extruded mesh. This is further followed by surface mesh and volume mesh.

So i wanna know how to do the sweep mesh by inflating the boundaries. This is because when i choose method as sweep mesh, i will not able to do inflation from the boundaries. So at the end, i try to change the SRC/TRG
from automatic to manual souce. Then i was able to create the mesh but not sure correct or not. Below some of the picture is the step i do the mesh with sweep method and inflation, i dont know is correct or not.

Hope someone can help me about this. Thanks you very much.

May you all be well and happy, alvin

Here is a very old picture I made back in 2014 (ANSYS R15.0) so some options would have improved since then (e.g. local rather than global inflation) but you could just do this and adjust the inflation to suit your simulation.

Thank you, Sir.
Sir, i got another question. What i need to do for this sentence "The inlet and outlet are subjected to extruded mesh. This is further followed by surface mesh and volume mesh"
This is because in the mesh part, i did not see any word like extruded mesh,surface mesh and volume mesh. Sir, did you have any ideas about this ?

May you be well and happy, alvin
