Swift brings the power of ODS Studio to Rhino and Grasshopper. Swift allows rapid design and analysis of commercial and residential building design. It brings together powerful industry-standard tools to create a platform for multi-physics simulation including CFD (including Wind, Air, Pollutant transport), Energy and Daylighting.
Requirements: Windows 10 (build 1607+ or higher), Rhino 5

Swift uses dictionary overrides to enable fast, clean and replicable setup of CFD case folders. This tutorial explains in detail how dictionary overrides are managed in Swift.
Simple External CFD (one wind direction)
This tutorial walks you through the setup of a typical CFD case in Swift. The case is a simple external CFD flow over some blocks for a single wind direction only.
Virtual Wind Tunnel (multiple wind directions)
This shows the setup of a case for the calculation of multiple wind directions using the Virtual Wind Tunnel. In this case 8 wind directions are solved. The Virtual Wind Tunnel is the basis for many more advanced calculations such as wind and urban comfort mapping and assessment of facade pressures.
Virtual Wind Tunnel (Advanced 1)
This shows the setup of a Virtual Wind Tunnel with two advanced features: 1) starting from a circular mesh to give a more effective use of the turtable area; and 2) overriding the boundary conditions for particular angles (during run-time) in order to simulate varying terrain around the site of interest.
Wind Comfort Mapping (Lawson Criteria)
This tutorial demonstrates the use of the Virtual Wind Tunnel to assess the percentage of time that wind speeds exceed threshold velocities. The results from this calculation may be used to map regions according to the Lawson Criteria for wind comfort.
Facade Pressure Analysis
This tutorial extracts facade pressures over an object for all wind directions calculated using the Virtual Wind Tunnel. The results are then imported back into Grasshopper as lists so that further analysis and processing may be done.
ODS OpenFOAM (v2.x) Extensions
Extra utility functions for OpenFOAM which work with Swift. These are required to be compiled on your platform in order for Swift to have full functionality with advanced features like the Virtual Wind Tunnel, Wind Comfort Mapping and Facade Pressures.
