across
(To be removed) Establish relationship between component variables and nodes
across will be removed in a future release. Use
equations instead. For more information, see Define Relationship Between Component Variables and Nodes.
Syntax
across( variable1, node1.variableA, node2.variableB
)
Description
across( variable1, node1.variableA, node2.variableB
) establishes the following relationship between the three arguments:
variable1 is assigned the value (node1.variableA –
node2.variableB). All arguments are variables. The first one is not
associated with a node. The second and third must be associated with a node.
The following rules apply:
All arguments must have consistent units.
The second and third arguments do not need to be associated with the same domain. For example, one may be associated with a one-phase electrical domain, and the other with a 3-phase electrical.
Either the second or the third argument may be replaced with
[]to indicate the reference node.
Examples
If a component declaration section contains two electrical nodes, p
and n, and a variable v = { 0, 'V' }; specifying
voltage, you can establish the following relationship in the setup section:
across( v, p.v, n.v );
This defines voltage v as an Across variable from node
p to node n.
