Problem
What are the differences between the pressure junction, transition and manhole elements?
When should I use the element type transition node versus a manhole with the structure type set to transition node?
Solution
The most appropriate element type depends on what it will be used to simulate. The following lists differences between the elements Transition and Manhole (Structure Type: Transition Node).
|
|
Pressure Junction
|
Transition
|
Manhole
|
|
Has a structure that extends vertically?
|
No
|
Yes, if "Set Top to Ground Elevation?" is set to False.
|
Yes
|
|
Can surcharge and pressurize?
|
Yes
|
Yes
|
Yes, if "bolted cover" option is set to True.
|
|
Can have inflow?
|
Yes
|
No
|
Yes
|
|
Can overflow into surface storage?
|
No
|
No
|
Yes, if "bolted cover" option is set to False.
|
|
Can have cross-sections as upstream and downstream node elements if connected by a channel/
|
No, can't connect to channels.
|
No, can't connect to channels.
|
Yes
