Hello Friends

i'm new in fluent. can some one help me to solve this simulation with fluent:

The flow field is a square enclosure with an aspect ratio of unity and length of 1 meter. The horizontal walls of the cavity are assumed to be insulated while the vertical walls are maintained at constant and uniform temperatures. The temperature gradient between the two vertical walls is maintained at a constant value of 20K (283K for cold wall and 303K for hot one). The cavity is filled with a nano-fluid made up of water and copper nano-particles (Cu).

My questions:

- What's the best meshing method and size?
- In material edit, with option should be selected for Density?
- What's the best Solution Method for momentum and energy

Thanks in advance.
