This information is part of the Modelica Standard Library maintained by the Modelica Association.
A model or block definition may contain the annotation defaultConnectionStructurallyInconsistent
.
annotation"(" defaultConnectionStructurallyInconsistent "=" ( false | true ) ")
If true
, it is stated that a default connection will result in a structurally inconsistent model
or block
.
A "default connection" is constructed by instantiating the respective model
or block
and for every input u
providing an equation 0=f(u)
, and for every (potential,flow) pair of the form (v,i)
, providing an equation of the form 0=f(v,i)
.
It is useful to check all models/blocks of a Modelica package in a simple way. One check is to default connect every model/block and to check whether the resulting class is structurally consistent (= a stronger requirement as "balanced").
It is rarely needed; but can be used for InverseBlockConstraints, in order to prevent a wrong error message. Additionally, when a user defined model is structurally inconsistent, a tool should try to pinpoint in which class the error is present. This annotation avoids then to show a wrong error message.
