Defines a potential root node.
Connections.potentialRoot(A.R); Connections.potentialRoot(A.R, priority = p);
The overdetermined type or record instance R
in
connector instance A
is a potential root node in a
virtual connection graph with priority p
(with p
≥ 0
). If no second argument is provided, the priority is
zero. p
shall be a parameter expression of type
Integer. In a virtual connection subgraph without a Connections.root()
definition, one of the potential roots with the lowest priority
number is selected as root.
This definition may be used if in a model with connector
A
the overdetermined record A.R
appears
differentiated, der(A.R)
, together with the constraint
equations of A.R
, i.e., a non-redundant subset of
A.R
maybe used as states.
