![]() ![]() Given that one has an input mesh format acceptable for PROTEUS, we have constructed several tools which allow more » 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. ![]()
