I'm looking for any refernces, tips, examples, etc. of 
natural convective heat transfer using FEM.

I'm doing work on a FEM program to calculate velocity and
temperature profiles along the boundary layer of a flow along
the length of a heated cylinder.

I'm not sure how to treat the continuity equation.  Usually in
fluid flow (convective) problems FEM methods treat the continuity
equation as a parameter and use either Lagrange (sp?) multipliers
or penalty parameters.  Since these both use the gradient of the
pressure, these methods are not useable in natural convection.
I do not want to use stream functions if I do not have to.

Also, I've never done a FEM program in cylindrical coordinates.
Any help or references would be appreciated.

Thanks in advance
