This is an interesting new plugin for SketchUp geared towards urban and architectural air flow studies:
Khamsin is a plugin extension of Google Sketchup which will aim to provide an integrated environment to conduct CFD analysis. Khamsin currently interacts with the existing third-party software Gmsh and OpenFVM for meshing, analysis and post-processing purposes. The long term goal of Khamsin is to become an integrated CFD package tailored for the building environment (wind studies, indoor air quality, thermal comfort), using 3D environment already in use by architectural practices.
Khamsin version 0.1 includes:
- Support tetrahedral meshing by Gmsh;
- Support thermal and airflow analysis by OpenFVM;
- Client-server configuration.
More information and downloads are available at Khamsin.
