SAFE integrates all aspects of the engineering design process into one intuitive and easy-to-use environment. SAFE offers engineers unmatched productivity with its unique combination of power and comprehensive capabilities. CSI solvers are tried and tested in the industry since over 45 years. The SAPFire engine can support multiple 64 bit solvers to optimize analysis and can perform Ritz and Eigenanalysis. Parallelization options can be used to take advantage multiple processors. SAFE provides a single-user user interface for modeling, analysis and design. A new model navigator is available to quickly access objects, properties and forms. SAFE is perfect for modeling footings, foundations, and basemats. Model soil supports and zero-tension soil models easily with uplift analysis. The subgrade modulus is used to determine the area of soil supports.
