FluidOne

xplore fluid mechanics through 36 interactive flow and wave models. Change physical parameters, inspect velocity, vorticity or pressure where the model defines them, and connect the picture to its governing equations. Study steady and unsteady viscous flows, potential flows around bodies, vortex dynamics, boundary-layer and low-Reynolds-number models, and surface or interface waves. Model-specific controls state their SI units and accepted ranges. Time controls reveal diffusion and motion. Component profiles, surface-pressure curves and wave-height profiles help reveal important structure. Read the included 365-page English theory textbook offline. It explains foundations, derivations, assumptions, worked examples and limitations. Use the native PDF reader to search, navigate chapter bookmarks and export a copy. The separate English user manual provides reproducible walkthroughs for every module. Probe a point or export a sampled field as CSV with the model, parameters, time and coordinate conventions. Unsupported quantities remain clearly identified, and solid or singular regions are excluded from ordinary sampling. Designed for iPad and Mac. No account, advertising, tracking, subscription or network connection is required for calculations and manuals. Exploration values are temporary; exported CSV records your parameters and sampled results. FluidOne is an educational model library. It is not a general CFD solver and does not simulate turbulence, breaking waves, stall or unrestricted three-dimensional flow. Linear-wave, boundary-layer, inviscid and creeping-flow assumptions remain important. English only. Requires iPadOS 17 or later, or macOS 14 or later. iPhone is not supported.
