Numerical Model

Hello,
I'm going to setup a new CFD simulation where I have both fluid-dynamic and heat exchange and both solid and fluid materials. I'm starting with Steady State analysis.
Heat exchange is both for conduction (in the solid and in the fluid) and convection.
I'm meshing with ICEM TETRA+PRISM and simulating with CFX.
What do you suggest as Solver Control parameters/setup (Turbulence Model, Timescale, etc.)?
Thank you very much for your suggestions

If the flow is turbulent then use a turbulence model. Check the Reynolds number of your flow for this. The CFX documentation and tutorials show how to set basic simulations up.
