Scalable Interfaces for Geometry and Mesh based Applications

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...

RGG Training Offerred

Posted by in News, RGG

RGG is an open source tool for generating several types of nuclear reactor assembly/core geometry and mesh. Two specific mesh operations implemented as per the graph-based approach are AssyGen and CoreGen. Reactor core model generation can be broken into three steps: assembly geometry creation (AssyGen), assembly meshing (AssyGen+CUBIT/MeshKit-Algorithms) and core mesh creation (CoreGen)....
