A new concept is presented on how to set up the equations of complex fluid networks. This concept avoids the creation of large non-linear equation systems and hence leads to a very robust modeling approach while still being competitive in levels of performance. The concept has been implemented in Modelica and tested for the rapid pre-design of aircraft environmental control systems.
