-**IMPORTANT**: In REX/PSI, the barrier zone inlet does **not** begin where the barrier web emerges from the main web, **but only** at the position where the melt channel begins. An initial melt channel width b_s_0 (> 0 mm) must be specified at the start of a barrier inlet zone. For example, if the melt channel starts with a radius of 2 mm between the barrier and main web, the initial channel width of the melt channel is assumed to be 4 mm and the start of the barrier zone is also set to this position.+**IMPORTANT**: In REX/PSI, the barrier zone inlet does **not** begin where the barrier flight emerges from the main flight, **but only** at the position where the melt channel begins.

-The barrier zone begins with the barrier walkway and ends with the barrier walkway. The position for determining the channel width is therefore on the barrier web. The position where the barrier web begins (in REX/PSI, i.e. where the initial width of the melt channel is specified) determines the initial aisle widths of the barrier zone (coordinate x=0 in the following figure). +The barrier zone begins with the barrier flight and ends with the barrier flight.

-This means that the passive (non-driving flank) of the barrier web determines the position for determining the aisle width as a function of the coordinate x in the axial direction.

However, as can be seen in the figure, the channel width is always determined orthogonal to the main flight.
  
-In the entry and exit zones, only the aisle widths at the zone transition (b_f/s_00 and b_f/s_11) are specified.
