Read MoreWith 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...

Read MoreThe 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...

Read MoreRGG 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)....
Read MoreWelcome to the documentation pages for SIGMA. This site contains the consolidated information about all things related to the ANL’s ITAPS implementation of iMesh, iGeom, iRel interfaces in the SIGMA suite of codes namely MOAB, CGM, Lasso respectively. Advanced mesh generation algorithms and tools to simplify complex creation of unstructured, highly resolved meshes for various geometries...
