The discontinuous slope is the upstream element of a pair of boundary elements simulating a change in slope. The corresponding downstream element is the discontinuous opening. Both are illustrated in Figure 83. The following constants have to be specified on the line beneath the *FLUID SECTION,TYPE=CHANNEL DISCONTINUOUS SLOPE card:
The length is typically small compared to the length of the adjacents
channel branches. Since storage for 9 items is provided and only 8 entries are
allowed per line, an extra blank line has to be provided for the ninth dummy
item.
Notice that a discontinous slope element generally has upstream channel elements attached to it. Therefore, it is always mandatory to specify an upstream reference element.
