This report is designed to explain RGG v 2.0 interface and provide users with the knowledge and skills to pilot RGG successfully. RGG interfaces with MeshKit tools to consolidate the meshing process, meaning that going from model to mesh is as easy as a button click. By integrating a 3D view of the reactor with the meshing tools and combining them into one user interface, RGG streamlines the task of preparing a simulation mesh and enables real-time feedback that reduces accidental scripting mistakes that could waste hours of meshing. RGG uses Argonneâ€™s SIGMA interfaces, Qt and VTK to produce an intuitive user interface. RGG is a program designed to aid in modeling and meshing of complex/large hexagonal and rectilinear reactor cores.

This report gives documentation for using MeshKitâ€™s Reactor Geometry (and mesh) Generator (RGG) GUI and also briefly documents other algorithms and tools available in MeshKit.

The former allows the conversion between most mesh types handled by PROTEUS while the second allows the merging of multiple (assembly) meshes into a radial structured grid. The most important mesh tools for any user to consider using are the MT_ MeshToMesh.x and the MT_RadialLattice.x codes. In many cases the examples are provided with a regression test of the mesh tools.

This report describes the various mesh tools that are provided with the PROTEUS code giving both descriptions of the input and output. Given that one has an input mesh format acceptable for PROTEUS, we have constructed several tools which allow further mesh and geometry construction (i.e. The NEMESH is a way for the user to create their own mesh or convert another mesh file format into a PROTEUS input format.

The UFmesh input allows for simple assembly mesh generation while the GRID input allows the generation of Cartesian, hexagonal, and regular triangular structured grid geometry options. At present, the UFMESH is a simple way to generate two-dimensional Cartesian and hexagonal fuel assembly geometries. There are three input means to create a mesh in PROTEUS: UFMESH, GRID, and NEMESH. As a consequence, significant effort has been put into place to create multiple codes that help assist in the mesh generation and manipulation. Given the complexity of real world problems, experience has shown that using commercial mesh generator to create rather simple input geometries is overly complex and slow. Similarly, PROTEUS-MOC and PROTEUS-NEMO were built to apply the method of characteristics on unstructured finite element meshes. In addition, the PROTEUS-SN solver was built to solve the even-parity transport equation on a finite element mesh provided as input. PROTEUS is built around a finite element representation of the geometry for visualization. (ANL), Argonne, IL (United States) Shemon, Emily R [Argonne National Lab. (authors)Įnergy Technology Data Exchange (ETDEWEB) Several RGG applications - 1/6 VHTR model, 1/4 PWR reactor core, and a full-core model for Monju - are reported. We also discuss the parallel-enabled CoreGen, which in several cases achieves super-linear speedups since the problems fit in available RAM at higher processor counts. In this paper, we present the current state of tools and new features in RGG. After one or more assembly model meshes have been constructed, a tool called CoreGen uses a copy/move/merge process to arrange the model meshes into a core model. Next, the assembly model or models are meshed by using MeshKit tools or the CUBIT mesh generation tool-kit, optionally based on a journal file output by AssyGen. First, assembly geometry models of various types are generated by a tool called AssyGen. The methodology operates in three stages.

It is released as open source software as a part of the MeshKit mesh generation library. The reactor geometry (and mesh) generator RGG takes advantage of information about repeated structures in both assembly and core lattices to simplify the creation of geometry and mesh.
