Information

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

8th test example: TwoMass

Two thermal capacities are coupled with two parallel coolant flow. Different initial temperatures of thermal capacities and pipe's coolants get ambient's temperature, the time behaviour depending on coolant flow.
