FISSICU platform on CRESCO-ENEA grid for thermal-hydraulic nuclear engineering (CIRTEN Report CERSE-UNIBO RL 1302/2010, XCIRTEN-LP5-004)

The FISSICU (FISsione/SICUrezza) platform for CFD thermal-hydraulics is set on the CRESCO-ENEA GRID cluster located in Portici. The platform contains codes for microscale, intermediate and system scale simulations for components of nuclear plants and facilities. For direct three-dimensional numerical simulations the platform contains codes such as TRIO_U and SATURNE. At intermediate scale the platform implements codes such as NEPTUNE and for system level CATHARE will be available soon. The platform contains the SALOME application for code coupling and a large number of mesh generators and visualization tools. All the codes run starting from mesh input files with common formats. GMESH and SALOME MESH are open-source reference mesh generators that can be found in the platform together with conversion tools. The output is written in common format and can be visualized through the PARAVIEW application. A brief guide through the platform codes and tools with reference mesh and output formats is presented.
