Couple of questions: please help
 

Hi everyone, new here and fairly new to cfd analysis. My intention is to analyse the flow around a half fuselage and then seperately wing.

My project is not centred around cfd but analysis is required to prove my design is feasible. I am looking for advise and ideas, to get general results:

What Clmax, Cp, total pressure, and density to expect?
Mesh, what type of mesh?
Size of mesh?
Angle of attack to set wing?
Do I set my density and temperature at sea level or ceiling
Do I use Vmax?
