Eddy is a Grasshopper plugin for wind and outdoor comfort simulation. Eddy focuses on annual ventilation analyses by employing both cylindrical and box-shaped simulation domains. Unlike other CFD tools with steep learning curves, Eddy is easy-to-use and features a straightforward user interface based on Grasshopper for Rhinoceros.

It helps architects and engineers to design sustainable and energy-efficient cities and empowers them with actionable ventilation and comfort metrics such as pressure coefficients and the UTCI and PET distributions.
