Information

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

This model demonstrates how to model the dissipated power of a drive train, by enabling the heatPort of all components and connecting these heatPorts via a convection element to the environment. The total heat flow generated by the elements of the drive train and transported to the environment is present in variable convection.fluid.
