NX Advanced FEM: High-end FEA pre/postprocessor NX CAE www.siemens.com/nx NX Benefits • Speed analysis modeling processes by up to 70 percent • Increase product quality by rapidly simulating design trade-off studies • Lower overall product development costs by reducing costly, late design change orders • Simplify CAE geometry editing processes with intuitive direct modeling • Rapidly update analysis models when the design geometry changes • Consolidate CAE preprocessing into a single environment supporting the most commonly used solvers • Efficiently manage large, complex analysis models through assembly FEM management • Capture and automate best practices and commonly used processes • Link results to product requirements to make smarter product decisions Summary NX™ Advanced FEM software is a comprehensive multi-CAD finite element modeling and results visualization solution that is designed to meet the needs of experienced CAE analysts. It includes a full suite of direct geometry modeling and editing tools as well as FE pre/postprocessing tools that support a broad range of product performance evaluation solutions. NX Advanced FEM provides bi-directional analysis model to design geometry association allowing users to rapidly update an analysis model when the base design changes. Multi-CAE environments enable analysts to build and export analysis models for industry standard solvers such as Abaqus, Ansys, LS- Dyna, MSC Nastran as well as NX Nastran® software. Analysts can also import results from these external solvers for postprocessing. A modern CAE environment NX Advanced FEM directly addresses the challenges you face with simulation today through a modern and completely integrated environment that delivers significant benefits. NX Advanced FEM does not require NX CAD and can be used as a standalone FEA pre/postprocessor with support for multi-CAD geometry. Although not required, when used in conjunction with NX CAD, NX Advanced FEM enjoys the added benefit of seamless data transfer between the design and analysis teams. NX Advanced FEM drastically reduces the time you spend preparing analysis models. It delivers all the advanced meshing, boundary conditions and solver interfaces that experienced analysts expect for high-end analysis. But what makes NX Advanced FEM unique among all other preprocessors
