Using a tool for daylight metrics it was not built to compute
Autodesk CFD and ANSYS Fluent can model light transport with physics coupling, but both are indirect for daylight metrics like glare and sDA, so additional post-processing is often required. BlenderBIM with daylight rendering extensions is strong for in-scene daylight visualization, but daylight analysis depth is limited compared with dedicated simulation platforms.
Skipping sensor grid planning and validation
DAYSIM requires careful sensor planning because scene setup and validation must align with geometry-driven study cases to produce meaningful daylight availability and glare metrics. Ladybug Tools also increases setup complexity when advanced sensor and weather inputs are missing or inconsistent with Rhino units and surface definitions.
Feeding physically inconsistent geometry or materials into the solver
Ladybug Tools depends heavily on clean model units and surface definitions because Radiance workflows can produce implausible results when geometry is inconsistent. DIALux workflows depend on correct inputs for materials, glazing, and orientation because incorrect optical inputs break the daylight-to-sensor mapping.
Underestimating CFD meshing and convergence effort for daylight-driven studies
Autodesk CFD depends heavily on mesh quality for stability and convergence, so large building models can require significant setup and tuning before daylight-driven comfort conclusions are trusted. ANSYS Fluent also demands demanding convergence tuning for daylight-specific studies, and geometric cleanup and meshing time can dominate early project cycles.
