Meshing a quasi-2D cylindrical wedge
 
Does anyone have any recommendations for meshing an axisymmetric cylinder? would it be better to use tetra or hexa mesh? Obviously the cell at the axis would have to be a prism if I did hexa the rest of the way out? But whatever I do looks like complete garbage of course, and I wonder if there are any guidelines to make it look halfway decent.

I sure do wish I knew Fluent right now!
CFX blows!!
I'd like to punch them in the face. (quoting King Odysseus form the movie Troy)

evcelica, finally you came out of the hardware section :p
it can be done using hexa only, do you have icem cfd among your tools ? come adress you problem in the ansys geometry and meshing section i'm sure you will get a lot of help

Hi Ali,

I do have ICEM CFD. I only asked here instead of on the meshing forum because it seems most users of other programs wouldn't have to worry about this problem.
I figured I could make the cell on the axis a prism, and the rest could be hexa, but I don't want to force it into something it doesn't like.
I'm doing a buoyant driven flow, which is already sensitive to mesh quality, and I worry about this poor quality wedge mesh making it even worse.
