I am moddeling flow around a cylinder with the goal to link windtunnel measurements to my simulation results. I opt to run my simulations in Ansys Fluent. I created a 2D grid/mesh according to several guidelines. However, I want to extrude this 2D mesh with a height of 2.5D (diameter of cylinder, in this case 75mm) and divide the extruded part in 64 partitions. How can I do this? I read a few thing about using CFX-Pre and extend the mesh in Z-direction. This approach should prompt a question that allows for this extrusion and division of elements. However, this question does not pop-up in my CFX-Pre 2021. Is there another way to create a 3D mesh?

You can do it in ICEMCFD.

I am utilising a student license and saw that this type of license does not support ICEMCFD. However, I found another solution.
Open Ansys Fluent Meshing -> File -> Import -> Fluent 2D Mesh -> 'select file'
Mesh (tab) -> Prisms... -> 'select boundary zones' -> 'set first height to the distance of the desired division in meters' + 'number of layers' -> apply -> create
Now the mesh is extruded into the Z-direction. What rests, is to split the surfaces from each other to assign the appropriate boundary conditions. This can be done under the tab Boundary -> Zone -> Separate. I added a figure of the result.
I hope this might be of any help to others.
