For the slope one can take the mean values of the slopes of the adjacent channels. The following constants have to be specified on the line beneath the *FLUID SECTION,TYPE=CHANNEL STEP card:
 
 (if
 (if  zero is taken)
 zero is taken)
 (if
 (if  the length is calculated from the
  coordinates of the end nodes belonging to the element)
 the length is calculated from the
  coordinates of the end nodes belonging to the element)
