and provides CAD import, modeling and meshing tools to create a finite element model, as well as postprocessing functionality that allows mechanical engineers to interpret analysis results. The finite element method allows engineers to virtually model components, assemblies, or systems to determine behavior under a given set of boundary conditions, and is typically used in the design process to reduce costly prototyping and testing, evaluate differing designs and materials, and for structural optimization to reduce weight. Product simulation applications include basic strength analysis, frequency and transient dynamic simulation, system-level performance evaluation and advanced response, fluid flow and multi-physics engineering analysis for simulation of functional performance. Femap is used by engineering organizations and consultants to model complex products, systems and processes including satellites, aircraft, defense electronics, heavy construction equipment, lift cranes, marine vessels and process equipment.
