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.

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.

In Verification, Validation, and Optimization, you can find information on how to carry out verification and validation tasks using Simscape Fluids and learn to use Simulink® Design Optimization™ to optimize block parameters.

In Modeling Options, you can learn to use blocks with pre-parameterizations or fault modeling support.
