As of 2020, CGM development has been stopped and the library will be completely deprecated and unsupported. No further development will take place to improve the library due to lack of specific funding for geometry handling workflows. Additionally, it requires too much effort to maintain and improve the library for usage on the next-generation hybrid architectures. We will eventually transition...

Details on compatibility of the different tools and dependent libraries are available separately and all questions can be directed to <package>[email protected]. Current release contains the following SIGMA tools: Common Geometry Module (CGM) – Version 16.0 Mesh Oriented datABase (MOAB) –...
Read MoreOver the past several months, the SIGMA team has been making use of containers with Docker to speed up testing on various cloud based platforms such as Codeship, Bitbucket-Pipelines and CircleCI (CGM, MOAB). This has been an area of active interest to us in making the libraries more robust, and is continually enabling us to create well integrated components within the SIGMA toolkit. The...
Read MoreGenerating conformal hexahedral meshes with boundary layers for urban buildings and atmosphere is a challenging task. We have created a tool that reads a .geojson file with 3D building models and creates a CAD model and mesh for the buildings and the urban atmosphere for CFD simulations. We are looking at different strategies to automate the entire CFD model creation process. The same geometry...
