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!

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.
