FLUENT problem for newbie

I have run a few 2d, steady state, single phase heat transfer models. No problem.
Basically, natural convection of water over a heated isothermal flat plate (I'm building up to more complex simulations). I want to repeat the simulation with a modified surface (my research). I wanted to apply an isothermal condition at the bottom of the structures and see how the temperature varies through it. So now I would apply an isothermal condition at the base of the structures. The problem is I don't know how to have the two different materials (solid and fluid) in the model. |

Make sure that in your meshing, the fluid and solid parts are two domains. In FLUENT, under cell zone conditions, apply the respective domains as solid and liquid.

Hi,
I am modelling a solidification problem in a square enclosure. I want the material inside the enclosure to be selected as a fluid. For this, i defined the new material( say liquid_metal), and applied this in the CELL ZONE condition tab and selected the type as fluid. However when I write a Initialization UDF, I use a if(FLUID_THREAD_P(t)) structure reference to initialize liquid fraction to 1. However, still its showing zero only. Is this procedure of setting the Cell Zone condition correct? Thanks in advance |
