Mesh ANSYS Fluent

Hello
I have uploaded an image of a mesh that I would like to create. I want to create it in ANSYS Fluent in 3D. Which functions do I have to use for this?

The short answer is, you can't. You can get closer with a hexcore volume mesh and then adding inflation layers, but the image you are showing requires a structured mesh generator like icem-cfd, pointwise, etc. If you have access to these mesh generators, look at the structured mesh tutorials that come with the software, this should get you started.

You could use ANSYS design modeler to create a cube and ANSYS Meshing with a mapped face and choose one of the structured meshers. Inflation layers will indeed not work but you can make the mesh size sensitive to the distance from nodes and edges.

For such a geometry it might be better to use one of the tools already mentioned, or gmsh if you do not have a license for the commercial meshers.
