Eddy3D — Outdoor+

A Grasshopper plugin for microclimate simulations

UMCF (urbanMicroclimateFoam) is an open-source solver for coupled physical processes modeling urban microclimate based on OpenFOAM.

Key Features

🌊 CFD - Solves turbulent, convective airflow - Handles heat and moisture transport in the air subdomain

🏗️ HAM - Manages absorption and transport - Controls storage of heat and moisture in porous building materials

☀️ RAD - Calculates net longwave and shortwave radiative heat fluxes - Uses view factor approach

🌳 VEG - Solves heat balance for urban trees - Handles green surfaces

Acknowledgments

The plugin is based on the urbanMicroclimateFoam open-source solver based on OpenFOAM, developed by the Chair of Building Physics at ETH Zürich.
