You can create models of custom designs by assembling components provided in Simscape Fluids. For example, you can model custom directional valve configurations by connecting Variable Orifice blocks. You can include effects such as spool dynamics and hydraulic forces. Custom actuators, including digital hydraulic actuators, can be modeled by combining piston chambers and other components. You can create, parameterize, and document reusable hydraulic component models using Simscape Fluids.
With Simscape Fluids, you can select components and design controllers in heating and cooling systems. Heat exchangers, pipes, valves, and other components cover standard and custom designs.
Simscape Fluids enables you to model concentric pipe, shell and tube, cross flow, and other types of heat exchangers. You can model standard designs, including parallel or counter flow, single or multiple shell passes, and mixed or unmixed flow. Using foundation components, you can create custom heat exchanger designs. Parameterization options let you incorporate measured data to make sure your system is represented accurately.
The pipe components in Simscape Fluids enable you model flow dynamics within the pipe and heat transfer with the pipe wall. You can model engine cooling, oil transportation, and other fluid systems. You can add or neglect physical effects, such as compressibility, fluid inertia, and wall compliance, to fit the level of model fidelity to your design task. Phenomena such as water hammer can be reproduced using these components.
Simscape Fluids provides directional, flow control, pressure control and other types of valves. These components enable you to include thermostats in heating systems and valve manifolds in lubrication systems. You can create custom valve designs by assembling variable orifices and other restrictions into a new component.

Simscape Fluids provides tank components to model pressurized tanks and reservoirs. These components enable you to track the volume of fluid in applications such as water supply networks and transmission lubrication systems. You can use these models to determine design control algorithms, refine requirements for pump sizes, and determine steady-state flow rates and pressures.
The analysis capabilities in Simscape Fluids enable you to rapidly explore and improve the performance of your design. They also help you ensure that your Simscape Fluids model has the right amount of detail for your task.
Using the Simscape Results Explorer, you can explore the simulation results for Simscape Fluids models, including variable values and the timing of events. You can navigate directly from plots of the results to the model (blocks and individual equations) to investigate the causes of the behavior you see. Using MATLAB code, you can automate any analysis, including time-based, frequency-based, and event-based analyses.
To identify computationally intensive portions of your model, you can measure the complexity of your Simscape Fluids model in quantities such as variables, equations that can trigger events, and constraints. This helps you determine if your changes are likely to improve the performance of the model during simulation. The Simscape Statistics Viewer links directly to the model (blocks and variables) to help you adjust model fidelity.
Simulink® capabilities enable you to solve challenging control design problems using Simscape models. Advanced linearization and automatic control tuning techniques help you apply complex control strategies and find controller gains that achieve robustness and response time goals. Profiling and advisor tools identify bottlenecks in your simulation and help you improve your model.
Simscape is the platform for all Simscape add-on products. In addition to the Foundation libraries, it provides much of the core technology for modeling and simulating physical systems in all domains.
Simscape components represent physical elements, such as pumps, motors, and op-amps. Lines in your model that connect these components correspond to physical connections in the real system that transmit power. This approach lets you describe the physical structure of a system rather than the underlying mathematics. Electrical, mechanical, hydraulic, and other physical connections are represented in your multidomain schematic by lines whose color indicates their physical domain. You can see right away which systems are in your model and how they are connected to one another.

Simscape Fluids is based on Simscape, which provides much of the core technology and capabilities necessary for modeling and simulating physical systems in all domains. Simscape enables you to:
The Simscape family of products consists of six products that cover a range of applications. You can combine any set of the Simscape add-on products with the Simscape platform to model multidomain physical systems. The add-on products include more advanced blocks and analysis methods.
You can convert Simscape Fluids models into C code using Simulink Coder. Converting Simscape Fluids models to C code enables them to be used for tasks such as HIL testing and optimization where batch simulations are performed. Converting to C code also enables the sharing of protected models.
Simscape Fluids models enable you to test embedded control algorithms and controller hardware without using hardware prototypes. In addition to software-in-the-loop (SIL) and processor-in-the-loop (PIL) tests, converting your Simscape Fluids models to C code lets you run hardware-in-the-loop (HIL) tests. This enables you to test embedded controllers without endangering equipment and personnel, and increases your confidence that the system will behave as specified when you connect the controller to the real system.

Many engineering tasks, such as optimizations and parameter sweeps, require running many sets of simulations. Converting your Simscape Fluids model to C code enables the efficient execution of these tasks. You can accelerate individual simulations, and run batches of simulations in parallel over multiple processors or distributed across a computing cluster.
Simscape helps you make efficient use of your purchased software when sharing models that use Simscape Fluids. It also provides methods of sharing models while protecting your intellectual property.
Using Simscape Editing Mode, Simscape users can perform many tasks on models that use Simscape add-on products even if they have not purchased the add-on products. Those tasks include viewing, simulating, and changing parameter values in the model. As a result, your team can leverage advanced components and capabilities from the entire Simscape product family without requiring that each engineer purchase a license for each Simscape add-on product.

You can share Simscape Fluids models with other users while protecting your intellectual property. You can protect custom components defined using the Simscape language as well as subsystems containing Simscape Fluids components. Sharing these models lets other users run simulations, vary parameters, and convert them to C code, but prevents them from seeing the original implementation.
MATLAB, Simulink, and Simscape are used at many leading universities. Educators can use modeling and simulation with 3D visualization to engage students with realistic examples and make classroom theory come alive. Using simulation, students can prototype in a virtual environment, which encourages them to try out new designs and to explore the entire parameter space. Simulation enables them to optimize their designs in research projects and student competitions. Because these products are also used widely across industries such as automotive, aerospace, and robotics, graduating students who have experience with MATLAB, Simulink, and Simscape are in demand by employers.
