That tutorial was based on running the CFX-TASCflow (V2.11) rct.lam tutorial in CFX-5 (v5.7). Geometry Nomenclature The duct has a length Lx , a height Ly , and a depth Lz .The duct length is aligned with the x axis, the depth with the y axis, and the height with the z axis. The flow is assumed to be symmetric about an x-z plane that bisects the duct in the y direction and therefore only half the duct is modelled. One corner of the duct is assumed to lie at the origin. Figure 1 below shows the duct geometry. When the geometry was defined in the creation of the computational mesh, all faces of the domain were assigned names. The names of the inlet and outlet planes (at x 0 and x Lx ) are RCT_W and RCT_E, respectively. The names of the planes at y 0 and y Ly are RCT_S and RCT_N, respectively. The names of the planes at z
