Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

The segment model is part of the multiple line model. It describes one line segment as outlined in the M_OLine description. Using the loop possibilities of Modelica it is formulated by connecting components the number of which depends on the number of lines.
