Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
Simple model of circular (or any other closed shape) wall to be used for pipe (or duct) models. Heat conduction is regarded one dimensional, capacitance is lumped at the arithmetic mean temperature. The spatial discretization (parametern) is meant to correspond to a connected fluid model discretization.
