Simscape™ Fluids™ models physical systems as networks with assigned fluid domains and specialized components, such as isothermal liquid pumps, two-phase fluid heat exchangers, and gas-thermal liquid actuators. Each component has at least one Through and one Across variable that can be measured at its ports. For more information on block variables, see Variable Types, and for more information on modeling in Simscape, see Essential Steps for Constructing a Physical Model.
In Modeling Fundamentals, you can find information on the numerics behind the network approach, which can help you better design your simulation control and monitoring systems.
