03 Outdoor+

Generate a multi-resolution terrain mesh from input geometry with a solid base. OutdoorPlus

Creates a STL mesh from geometry using the gmsh application. Useful to create healthy mesh topologies for building elements.

Read an EPW file and create a Weather object for the simulation. OutdoorPlus

Select a building material from the list and override its properties.

Configure mesh refinement for building regions.

Configure mesh settings for terrain and underground regions. OutdoorPlus

Select a terrain surface material from the list and override its properties. OutdoorPlus

Configure mesh refinement for vegetation regions. OutdoorPlus

Define vegetation property coefficients for canopy modeling. Shows the recommended coefficients (Leaf Length, rsMin, kc) by default; right-click to show all coefficients (Cd, C, nEvapSides). OutdoorPlus

Create an air region for the UMF case. OutdoorPlus

Build a solid building region for the UMF case: from the façade surface meshes, two material wall layers (outer + inner) are extruded inward to model heat and moisture transport through the building envelope.

Create a terrain region with materials and depth settings. OutdoorPlus

Create a vegetation region from tree crown solids. Pick a Tree Type preset for a typical leaf area density and foliage drag coefficient, or choose Custom and wire your own LAD. The output drives BOTH the Outdoor+ (OpenFOAM/UMF) case and the LBM Run component's Vegetation input, with consistent canopy drag. Library sources — LAD (crown-average, m²/m³): Sjöman et al.

Note: NIST TN 2039 (2019) reports Cd ≈ 2.8 against total projected area per volume — a different normalization; do not mix it with the Cd·LAD convention used here. OutdoorPlus

Define simulation domain extents and refinement padding. OutdoorPlus

Configure snappyHexMesh settings for the simulation. OutdoorPlus

Configure simulation control settings for UMF. OutdoorPlus

Define simulation timing and optional weather-driven time series. OutdoorPlus

Configure the view-factor discretization for radiation modeling. OutdoorPlus

Create, read, and manage an Outdoor+ (UMF microclimate) case. OutdoorPlus

Run the OpenFOAM checkMesh command for a case region. OutdoorPlus

Tests for buildings and trees for Eddy3D-OutdoorPlus simulation.

Parses log files in a case folder and reports any FOAM errors. OutdoorPlus

Deconstruct a MetaFOAM Region instance.

Deconstruct a Weather object into hourly time series values. OutdoorPlus

Convert specific humidity (w) and temperature (T) to relative humidity (%). OutdoorPlus
