Main Components

FluidX3D Run
Prepare and launch a FluidX3D GPU wind simulation (builds the solver from source, runs on the GPU). LICENSE: FluidX3D (ProjectPhysX) is free for NON-COMMERCIAL use only — public research, education, or personal use. Commercial use is not permitted. See the FluidX3D LICENSE.
FluidX3D Run Settings
Solver controls for the FluidX3D GPU engine (memory, simulated time, export interval, and an interactive real-time window).
LBM Run
Prepare and launch a container-based OpenLB wind simulation (Smagorinsky LES, time-averaged pedestrian wind field). Uses the same ABL inflow object as the OpenFOAM and FluidX3D engines. Needs Docker Desktop or podman; the solver image is pulled on first run.
LBM Run Settings
Solver controls for the container-based LBM wind engine (grid spacing, warmup and averaging windows, probe layer, GPU, container runtime).
FluidX3D Live View
Watch a FluidX3D wind solve live in the viewport: colors an analysis mesh with the velocity magnitude of the newest exported frame while the GPU solver runs, updating as each frame lands. Also shows the final field of a completed run. Wire either the Run component's Case or Folder output into Case, and supply the mesh to read the wind on (e.g. a pedestrian-level plane).
LBM Field
Read the time-averaged pedestrian wind field from an LBM case directory. Outputs world-frame points and velocity vectors — plug both into the Wind Field Viewer.
