![]() ParaView is most commonly used, but the visualization procedure is similar for other programs. This format is supported by ParaView, VisIt, and other postprocessing applications. The Exodus output format is the preferred way to write out simulation results from MOOSE simulations. ![]() When you are satisfied with your mesh input, you may invoke MOOSE without the -mesh-only option to execute the entire input file (mesh building and physics input).Įxecutables of any MOOSE applications that contain the Reactor module in their Makefile can also be used, such as Griffin, Sockeye, Pronghorn, Cardinal, and BlueCRAB. Recent updates to the -mesh-only option now allow the mesh output in Exodus format to include the extra element integer IDs (see Reporting IDs: A Powerful Feature for Assisting with Physics Input and Output Processing) defined on the mesh by default for convenient visualization purposes. This is useful while building and testing the mesh as it doesn't require the rest of the MOOSE problem be defined in the input file. The -mesh-only optional command line parameter executes only the block of the input file and outputs the generated mesh. $MOOSE_DIR/modules/reactor/reactor-opt -i -mesh-only Use any executable with the Reactor module compiled (see Building the Reactor Module), such as $MOOSE_DIR/modules/combined/combined-opt or $MOOSE_DIR/modules/reactor-opt along with the -mesh-only command line option: Trim along lines of symmetry to reduce computational expense The meshing workflow for a standard reactor core follows the general hierarchical process of identifying key features in the geometry and building them hierarchically in terms of smallest to largest (pins, assemblies, core, core periphery):ĭefine assembly by patterning existing pins into a lattice and adding coolant background and/or duct regionĭefine core by patterning assemblies into a latticeĪpply core periphery zones like a circular shield In some cases where these configurations have been changed, these files might open in Notepad instead. By default, Excel files are configured to be opened with Excel. When you double-click on a file in Windows, the system knows which application to use to open it. Application of a peripheral core zone, trimming along symmetry lines and extrusion to 3D are optional in the final steps. Change the Default Settings for File Types. For example, after pins are defined, they can be patterned into an assembly, and assemblies can then be patterned into a core. To create a mesh, the user must define a sequence of MeshGenerator object calls inside the block to construct a geometry beginning with the smallest components (pins) and building up to larger components (core). MOOSE's Mesh System and Reactor Module contains numerous "MeshGenerator" objects which either (a) create a mesh from scratch or (b) perform operations on existing meshes.
