A free and powerful circuit designing software

FluidSIM is a robust application designed to help you create, simulate, and study digital, electro-hydraulic, electro-pneumatic, and electronic circuits. The free application combines the power of a circuit diagram editor with component descriptions, photos, animations, and videos. All these media files and functions interact seamlessly to provide users with an accessible, self-study application

Developed by Art System Software, the FluidSIM download is suitable for students studying different circuits. It features drag-and-drop circuit editing and allows users to add labels with comprehensive descriptions to each component. Furthermore, the circuit designing software offers simulation capabilities to process models and mathematical procedures. FluidSIM alternatives like LabVIEW, Digital Logic Design, and idealCircuit also offer similar features. 

What is FluidSIM?

FluidSIM is a circuit designing program that you can use to create, simulate, and study different types of circuits. These include electro-hydraulic, electro-pneumatic, digital, and electronic circuits. To create a circuit, you can use the app’s drag-and-drop mechanism and add items wherever you wish to view them. The free circuit editor also lets users add a detailed description, animation, photo, or video to all components.

Furthermore, FluidSIM has a simulation core that ensures users can test different models and conduct mathematical procedures. Since the application is also compatible with Festo EasyPorts, OPC, and DDE, it allows for easy communication with other applications and hardware. The application is quite comprehensive and suitable for students, hobbyists, and employees.

How do you use FluidSIM?

With the help of FluidSIM, you can easily create your first circuit in a matter of minutes. The program features a library of hydraulic, pneumatic, and electronic components that you can drag and drop onto your circuit design. You can also choose default parameters and observe the physical model instantly. Since the components library continues to evolve, you can easily find new and improved components for your circuits. 

Apart from functioning as a circuit diagram editor, FluidSIM features an interactive simulation core. It lets users calculate state changes and component switches to create an altered circuit. These changes and switches can be operated and activated by the user. In addition to this, the simulation controls allow users to transfer hardware signals from other programs and watch FluidSIM react in real-time.

Since FluidSIM features a diagnosis mechanism, users get access to failed models that show defects - all of which can be bypassed by editing the components. When used for study groups, FluidSIM lets users simulate defective components and correct their mistakes with help from the knowledge base. Failed components can be protected with a password to hide errors made by the learner. 

What are the advantages of FluidSIM? 

FluidSIM has a simulation core that has been designed to give maximum speed without hampering the results. With its help, you can simulate electrical signals up to a frequency of 100 kHz. This makes creating and testing circuits quite a simple process. Furthermore, users can run simulations to identify issues in components, and teachers can leave comments and documents for learner reference. 

Furthermore, users can utilize measuring devices to create and simulate their circuits. These Virtual Measuring Devices are available in the app’s diagnosis toolbar and can be used for electrical engineering, hydraulics, and electro-pneumatic circuits. Having said that, the measurements don’t influence the circuits but only indicate the values assigned to each. 

The diagnosis toolbar also consists of several variables for pressure, pressure flow, amperage, voltage, and more. All of these values are pre-defined so that users can access them and add them to their circuits without making too many edits. Apart from this, FluidSIM also features an extensive library of components and a large variety of didactic materials for better and faster circuit designing. 

Does FluidSIM offer any support?

One of the best parts about downloading FluidSIM is that it features an integrated ‘Simulating with FluidSIM’ tutorial that is useful to beginners. This tutorial explains the basics of electrical engineering, hydraulics, and pneumatics. It also provides a range of educational videos that help users get an in-depth knowledge of components and circuit diagrams.

The only drawback of the application is that in some cases it focuses more on the response time than on the accuracy of results. Having said that, the application still provides results that remain within the allowable limit range. 

What can users expect from the latest version of FluidSIM?

The latest version of FluidSIM covers a variety of simulations, including P, H, and E. It works as professional CAD software and lets users create drawings, projects, and printouts. Furthermore, all simulations take place in high definition and let users control variables using a joystick. The application also features an improved library and offers one license for multiple users. 

What are the advantages of using FluidSIM?

FluidSIM provides users with an advantage when developing and designing hydraulic systems and pneumatics. It comes with system visualization options and simulations that allow users to run different procedures and get a real-time advantage when creating circuits. It also provides students with a comprehensive learning environment, where they’re able to create, simulate, and correct circuit diagrams. 

Should I download FluidSIM?

If you’re looking for a circuit diagram editor, download FluidSIM. Designed for students, hobbyists, and employees studying electrohydraulic, electro-pneumatic, digital, and electronic circuits. It provides users with a platform to create and simulate circuits with different variables. It also lets users add instructions to circuits and their elements. 

Creating circuits with FluidSIM is quite easy as it lets users drag and drop various components and tweak them as needed. Furthermore, the application includes a vast library of components that continue to evolve and change. In addition to this, the app comes with a simulation core that lets users complete various mathematical procedures. It also lets users add labels containing photos, video sequences, and animations to all components and circuits.
