Hello All
I am working on IC Engine Fin problem with Fluent and got stuck so solving very simple 2D problem of Rod conducting heat from one end to ambient air around.

Here I have few questions for experts out there

1. At steady state 0 m/s velocity, I received the block temperature (150 deg) all over the body, even the fluid around.
to get more correct results i have switched on gravity with 9.81 m/s^2,
even worked on Air density to Boussinesq with thermal expansion coeff or even density to incompressible ideal gas (according to few lit.)
But no results!!

2. URF are affecting too much with convergence and results and if initialize with lower values (by mistake) solution look very different, please put a light on its affect and usage

We can discuss further if anyone turn up

thanks in advance
