boundary condition problem - NEED HELP

rave

friends,

I have a fuselage at the centre of a cubical box. I have created the volume mesh in the box for the flow around the fuselage. I want to assign the fuselage surface as a no-slip wall boundary condition, but i m not able to select the cell-set for this. the problem is tht, the fuselage is a closed body and thr r 3 EXTRUSION layers around it. i want to select the inner surface cell set for the wall boundary region. I tried to do it by keeping the clipped hidden view, but tht way not all the surface cells got selected. after this individually selecting the remaining cells is a TASK.

if sm1 can tell me any other way for defining the boundary region, I shall be thankful to him.
