The T-Junction mesh was generated for the OECD Vettenfahl T-Junction benchmark; this exercise was a blind benchmark of various CFD codes. The Argonne code Nek5000 participated in this benchmark, using the mesh shown below. The mesh was generated with Cubit 10.2, then modified to extend the (top) inflow and (side) outflow pipes. Mesh Cutaway view of volume mesh Shape quality metric for this...
Read MoreFacet based models are a useful format for file transfer, mesh generation, and efficient geometric computation. Solid modeling engines typically facet each surface independently. It is likely that the faceted boundaries of neighboring surfaces are not the same, especially for non-manifold models. Gaps, overlaps, and discontinuous topology can occur between surfaces. This is problematic for...

Read MoreEBMesh : Embedded Boundary Mesh generation tool EBMesh is an open source tool to generate Cartesian meshes for embedded boundary algorithms by using a ray-tracing technique. (a) (b) Input and output from EBMesh tool. (a) STL 3D “statue” and “horse” models. (b) Cartesian mesh elements of 3D STL models. By this tool, each mesh cell is distinguished as being inside, outside, or on the boundary...
Read MoreBuilding New MeshKit Algorithm to Python To bind a MeshKit algorithm to Python, you’ll need to add some SWIG code to meshkit/python/algs.i and meshkit/python/algs_factory.i. Specifically: algs.i (near the bottom) %include "meshkit/MyNewAlgorithm.hpp" algs_factory.i #include "meshkit/MyNewAlgorithm.hpp" … %factory(MeshKit::MeshOp * MeshKit::MKCore::construct_meshop, …...
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 MorePrerequisites: MeshKit may require iMesh implementation for its mesh data structure and, if you’d like to read geometry files, requires iGeom implementation, so you’ll need to build/install those first. In addition, if you’d like to relate mesh and geometry, requires iRel implementation. The implementations of these interfaces are part of SIGMA. Please follow instructions on...
