FluidSIM – Create, Simulate and Study Circuits


FluidSIM allows users to design, simulate, and study electropneumatic, electrohydraulic, and digital circuits. The program features an editor for diagram creation as well as component libraries with photos and descriptions as well as an advanced simulation core capable of handling various mathematical procedures.

This software comes equipped with an abundance of educational materials such as texts, images, training films and presentations to supplement its instruction. Furthermore, its integrated teaching program “Simulate with FluidSIM” introduces students to basic pneumatics, hydraulics and electrical engineering principles.

Easy-to-use interface

FluidSIM software enables users to design and simulate digital, electrohydraulic and pneumatic circuits easily and free. With an ever-expanding library of components – as well as label capabilities to add photos, animations and videos for every component – and its simulation core offering testing models along with mathematical procedures; Festo EasyPorts OPC DDE communications allow seamless collaboration among applications or hardware devices.

The program includes a state diagram that displays current flow and signal state for all connected devices. Furthermore, this allows learners to easily calculate status changes of switches and valves – or intervene directly by operating or switching them directly – which helps learners better understand how control systems function. This provides learners with an excellent opportunity to gain a more complete understanding of control system theory.

FluidSIM features not only a state diagram but also a virtual measuring device to identify defective components during simulations and determine their level of faultiness. FluidSIM employs a novel diagnosis concept which stores error models that depict typical component issues before creating an error configuration through dialogue before simulation starts, so faulty parts can be found by virtual measuring devices during the simulation and directly fixed afterwards.

Users can quickly design pneumatic circuits using this intuitive software’s user-friendly interface and animated visualizations that help explain complex concepts. Ideal for both students and professionals alike, its versatility enables it to be tailored specifically to each user.

Setting the number of licenses for local installation, network usage or homeschooling can be particularly helpful. This enables multiple learners to have simultaneous access without fear of overusing or losing your licenses – plus you can transfer licenses between students whenever needed! With its comprehensive tools and flexible settings capabilities, mechatronics education couldn’t be made simpler!

Virtual measuring devices

The software program enables users to utilize virtual measuring devices for electrical engineering, electro-pneumatic, and hydraulic circuits. These tools are housed within the diagnostic toolbar for easy use in measuring pressure, pressure flow, amperage, voltage without altering the circuit itself. The toolbar also includes labels containing photos, animations, video sequences for all components allowing easy creation, simulation, study of different circuits as well as mathematical operations being conducted through its simulation core.

This simulation software is ideal for students and teachers as it features an expansive selection of components and educational materials to facilitate faster circuit creation. Furthermore, its many useful functions make structuring lessons simpler while its free circuit editor lets users add detailed descriptions, component photos, cross-sectional animations for all components. Festo EasyPorts OPC DDE support ensures smooth communication with other hardware.

FluidSIM’s simulations aim for realistic representations rather than stylizations of fluid dynamics, and its FLIP solver allows realistic simulation of all forms of fluid such as gases and liquids – an advantage over particle-based smooth Particle Hydrodynamics (SPH) simulation models which require significantly more computing power in order to appear realistic.

FluidSIM offers more than just FLIP solving; it also features an innovative diagnosis approach. By storing error models for individual components that represent typical defect scenarios and quickly consolidating them using dialogue into an error configuration, FluidSIM helps the user identify defective components during simulations and correct them virtually – directly translating learning experiences to real world applications.

Furthermore, it enables the user to transfer hardware signals via an interface into the system and monitor how an altered circuit functions in real time – a distinct advantage over programs which simply provide static diagrams without interactive simulation features.

Error configurations

FluidSIM features libraries with pneumatic, hydraulic and electrical engineering components from across all three categories of engineering disciplines, as well as extensive didactic material from its “Simulate with FluidSIM” learning program – providing students with access to an expansive variety of topics to study while making structuring lessons straightforward.

Simulation software supports various error configurations to assist with pinpointing specific systemic errors and pinpoint their cause. If a problem arises, an error message will appear in the Simulation Diagnostics window detailing more about its source; should corrections need to be made to avoid further problems from occurring, an alert will also be displayed here.

Error messages often indicate that the solver was unable to produce a consistent solution to algebraic constraints at the start of transient initialization, typically when multiple dynamic states depend on each other due to nonlinear algebraic relationships such as two inertias linked via an elliptical gear interacting nonlinearly with each other. When this occurs, additional error messages including warnings about component equations as well as blocks involved may appear in the Simulation Diagnostics window in relation to that dependent dynamic state.

Another frequent type of error arises when the model contains components which cannot be connected in real-world circuitry, either due to misconfiguration of block types or violating grounding rules (for more details please see Best Practices). If an error message indicates that this system cannot longer be solved, try simplifying its components.

Systems may also experience issues when components are improperly modeled or don’t function together as intended, prompting simulation software to display error messages in its Simulation Diagnostics window that provide students with additional details and suggest possible solutions for such problems. When this occurs, students can rely on simulation software’s error messages in its Simulation Diagnostics window as an informative way of finding solutions.

When the Simulation Diagnostics window indicates that the system failed to converge or that no consistent initial conditions could be generated, this may indicate an issue with dynamic state equations and/or parameter discontinuity. Such issues usually surface towards the end of a transient simulation step and can be addressed by increasing Consistency Tolerance parameters within Solver Configuration blocks.
