Docker container for SIGMA

Posted by in News, SIGMA

Over 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...

Urban Modeling

Posted by in Meshes, Meshkit, News, RGG, SIGMA

Generating 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...
