Modeling Fundamentals and Processes

Modeling techniques, constraints, and best practices for fluid systems

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 Basic Principles of Modeling Physical Networks, and for more information on modeling in Simscape, see Essential Steps for Constructing a Physical Model.
