Thanks Dave,

The idea you proposed works great. so basically I did place a local coordinate and rotate then I used Esel to select the required elements as Bellow:   

LOCAL,12,1,0,Dc/2,pos_z,,,theta,r 
   CSYS, 12
  ESEL, S, CENT, z, -b/r,b/r
  ESEL, r, CENT, x, -b,b

Many thanks again for your valuable feedback
