Scalable Interfaces for Geometry and Mesh based Applications

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...

Lasso library obsolete

Posted by in Lasso, News, SIGMA

With the consolidated release of SIGMA v1.2 announced today, we are officially deprecating and rendering obsolete the usage of the Lasso library, as an explicit dependency in SIGMA. Lasso provided the iRel (ITAPS) implementation that exposes support for relational queries between geometry and mesh entities. Due to a strategic decision to tightly integrate geometry-mesh queries for a varied...

Featured: RGG and Kitware

Posted by in News, RGG

The July issue of Kitware news has a featured article on the collaborative effort between one of our own, Rajeev Jain (MeshKit/RGG) and the Kitware team funded by DOE Nuclear Energy Fast Track SBIR. Kitware has developed an open-source GUI tool that is integrated with RGG while leveraging Kitware’s existing projects including the Computational Model Builder (CMB), VTK, and ParaView, to...
