Information

Defines required branch of spanning-tree

Syntax

Connections.branch(A.R,B.R);

Description

Defines a branch from the overdetermined type or record instance R in connector instance A to the corresponding overdetermined type or record instance R in connector instance B for a virtual connection graph. These branches are required to be part of the spanning-tree for the virtual connection graph (they do not directly generate equations, but should be combined with equations coupling A.R to B.R), whereas connect-statements are optional for the spanning-tree (and generate different equations depending on whether they are part of the spanning-tree or not).

Examples

This function can be used at all places where a connect(...) statement is allowed.

E.g., it is not allowed to use this function in a when-clause. This definition shall be used if in a model with connectors A and B the overdetermined records A.R and B.R are algebraically coupled in the model, e.g., due to B.R = f(A.R, <other unknowns>).
