across
Establish relationship between component variables and nodes
Syntax
across( variable1, node1.variableA, node2.variableB
)
Description
Note
across
will be removed in a future release.
Use equations instead. For more information, see Define Relationship Between Component Variables and Nodes.
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
.
