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.
Fast probe multiple patches
Probing of the results on arbitrary groups of points. This could be, for example, probe points above each balcony of a large building.
Virtual Wind Tunnel (Advanced 1)
This shows the setup of a Virtual Wind Tunnel with three advanced features: 1) starting from a circular mesh to give a more effective use of the turtable area; 2) overriding the boundary conditions for particular angles (during run-time) in order to simulate varying terrain around the site of interest; and 3) defining terrain types (eg. countryside, suburban and urban) in a nice drop-down list to select for the boundary condition.
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.
Buoyant Boussinesqu PIMPLE
Transient heat-transfer using the BuoyantBoussinesquPimpleFoam solver. To run the SIMPLE (steady-state) solver, just replace the solver definition with "buoyantBoussinesquSimpleFoam".
Remote Execution over Network
Setup of the "simpleExternalCFD" demo including the configuration and instructions for setting up and running over a network from your local machine. This allows you to use a lot of CPUs available over your network.
