Click the green button in the top toolbar. The lines will immediately color-code. Click and hold the lever on the 4/3-way valve symbol. The valve spool shifts, fluid flows through the flow control valve, and the cylinder extends at a controlled speed. Release the lever to see the cylinder stop mid-stroke.

The FluidSim 4.2 Hydraulics Student Version offers several key features that make it an effective tool for teaching and learning hydraulics:
Version 4.2 introduced support for drawing and simulating GRAFCET diagrams—a sequential function chart standard for describing the behavior of automated systems. This allows students to design complex control sequences and verify their logic before implementing hardware solutions. The valve spool shifts, fluid flows through the
To understand the student experience, let us walk through a classic lab exercise: Controlling a double-acting cylinder with a spring-return 4/2-way valve.
Connect the to the T port of the 4/3-way valve.
: The interactive core calculates state changes instantly, allowing students to activate switches and change valves while the simulation is running. Dynamic Analysis
