Because of broad industrial usage, structural mechanics codes are generally very well developed in comparison to codes in other physics areas. Instead of independently developing structural mechanics codes, ORNL integrates the capabilities of commercial structural mechanical solvers like ANSYS and Abaqus with other physics codes to solve multiphysics problems. ORNL also maintains a structural mechanics analysis capability in the commercial simulation framework COMSOL for application in multiphysics simulations, including flow-induced vibration. For HFIR’s low-enriched uranium (LEU) conversion and experiment design, ORNL expertly applies the commercial ANSYS thermomechanics software.
