05 Outdoor Results

Sample fields at points on a solved case, post-hoc. With Run it writes a probes function and runs postProcess on the latest time, then reads the results; without Run it reads existing results. Works on a wind case (one sub-result per direction) or a loaded case.

Draws a wind case's residual convergence directly on the Grasshopper canvas, with lightweight timed updates. Wire the case and toggle 'Live' to monitor a running simulation without an external plotter window. When a warm-up ramp is enabled the solver restarts mid-run and writes a separate residual file per phase; all phases are stitched into one continuous curve so you see the full history (warm-up + main), not just the latest phase.

Monitor blockMesh, surfaceFeatures, and snappyHexMesh progress from the mesh case logs.

Compute volumetric flow rates (m³/s) across a mesh, treating its vertices as velocity probes. Per face: average vertex velocities × face area × cos(angle to face normal).

Classifies pedestrian wind comfort per point from an annual hourly wind-speed series (the Wind Speed output of the Velocity Amplification Factors (VAF) component) against a comfort criterion (Lawson, Davenport, NEN8100). Returns the comfort category, class letter, and activity description for each point.

Compute Velocity Amplification Factors (VAF) and annual wind speed at probes from CFD results and EPW weather data. VAF (the term used in the wind-engineering literature for what Eddy3D historically called "wind factors") is the local wind speed normalized by the reference speed.

Visualize a probed wind field: colored velocity arrows, a point cloud, a heatmap mesh, streamlines, or volumetric smoke (pick via Display Mode). Feed the Probe component's points + velocity vectors (Field = U), or any points + vectors.

Define an analysis period (from/to day of year, start/end hour of day) and output the hour-of-year indices it covers, for filtering annual results.

Convert a date and time (month, day, hour) into a single hour-of-year integer (1–8760), for indexing annual hourly data.
