Dear All,
I need to mesh only a front part of a fuselage. I done with meshing.. Now my question is,My guide gave me a iges file which contains only that front part of fuselage..Should i have to create a control volume for that fuselage and mesh?? or can i directly continue with my meshing .. generally, for airfoils, we create a control volume like rectangular or circle shapes etc .. should i create that for meshing this ??

using GAMBIT.!!!!

I need ur suggestions and guidelines.. Thanks in Advance..

yes of course if you want to analyze flow field around it then you have to have a suitable domain around the aerodynamic object.

how you are going to segregate the base drag. May be you get the higher values due to larger dia. So may be you want to extend the fuselage to far-field and put the free slip condition on extended surface.

you can use hemisphere at inlet and cylinder at outlet. Full sphere is also good option.
