Loss

At a glance…

The loss node loses flow based on a provided flow-loss relationship.

[node.high_flow_loss]
type = loss
loc = 20, 30
table = 0, 0,
        1000, 0,
        2000, 500,
        1e8, 1e7
ds_1 = node_below_loss

Node properties

Property Description
[node.?] (compulsory) Start of node declaration. This says we are creating a node, and also defines the name of the node. Node naming conventions are discussed at . Example: [node.high_flow_loss]
type (compulsory) The node type, which is “loss” in this case. type = loss
loc (compulsory) The location of the node in cartesian coordinates. Example: loc = 20, 30
table (optional) Loss table defines the relationship between the upsteam flow and the loss. Refer to this page to read more about in Kalix. Example: table = 0, 0, 1000, 0, 2000, 500, 1e8, 1e7
ds_1 (optional) Name of the downstream node. This property defines a downstream link. Inflow nodes may only have 1 downstream link. Example: ds_1 = my_other_node

Results associated with this node

Result Description
dsflow Total downstream flow (=ds_1) [ML]
usflow Upstream flow [ML]
ds_1 Downstream flow on link ds_1 [ML]
ds_1_order Orders on the link ds_1 [ML]
loss Amount of water lost at this node [ML]

How the node works

The flow on the secondary link is determine by interpolating the provided splitter table. This volume is sent to ds_2, and the remainder of the flow is sent to ds_1.

loss=f(usflow)

ds1=usflow−loss
