The program provides a wide range of state-of-the art constitutive models for tackling soil and rock materials in applications as diverse as foundations, embankments, tunnels, excavations, slope stability, mines and dams. The analysis capabilities for pore pressure and consolidation, groundwater flow, earthquake and liquefaction problems are some of the most advanced available and are essential for accurate analysis of these types of coupled problems. DIANA also offers advanced features to model steel and reinforced concrete structures that interact with the ground.
