3D inlet-flow visualization
DualSPHysics inlet-flow output processed through VTK/IsoSurface, Blender, and video assembly for a clear view of the simulation workflow.
Open on YouTubeSmoothed Particle Hydrodynamics Simulation & Visualization
Case study in turning GPU SPH simulation outputs into concise visual material for scientific review and explanation of model behavior, post-processing choices, and limits.
Simulation examples
Four hosted DualSPHysics videos show a practical path from particle-based solver output to readable media. The rectangular jet proxy extends the family into geometry metrics and model-overlay handoff while remaining a single-phase proxy, not validation media.
Dam-break workflow
A compact dam-break example showing how GPU SPH output can become a stable visual sequence for review and explanation.
Open on YouTubeImpinging-jet visualization
Includes reconstructed-surface view and scalar context for velocity, pressure, and density.
Open on YouTubeRectangular jet geometry proxy
Single-phase rectangular-inlet proxy with surface reconstruction, pressure and velocity diagnostics, cross-section views, and explicit validation caveats.
Open on YouTubeAnalysis bridge
The rectangular case is also the bridge into analysis workflows: solver-derived geometry proxies become reviewable metrics for the existing model-analysis tools without being presented as atomization or experimental validation.
Rectangular jet geometry proxy
A single-phase rectangular-inlet proxy adds surface reconstruction, velocity and pressure views, true cross-section cuts, and a SprayGeo / Ideal Momentum Jet Explorer metrics handoff.
Single-phase geometry proxy; not atomization validation.
Workflow
The case study connects numerical output, visualization choices, and communication needs without turning the visuals into validation claims.
- DualSPHysics GPU SPH simulation outputs
- VTK and IsoSurface post-processing
- Headless Blender rendering
- ffmpeg video assembly
- Solver metrics handoff into SprayGeo and Ideal Momentum Jet Explorer
- Visual QA and model-limit communication
Scope
The goal is to make simulation behavior and post-processing choices easier to review. The examples are bounded by the following scope.
- Visualization and post-processing study
- Not experimental validation
- Not production CFD
- Not atomization or breakup validation
