Siemens has strengthened and expanded upon the NX CAE allows you to achieve these benefits through a fully technologies from its long simulation legacy and has integrated environment that combines all of the following: brought them together to form NX™ CAE software. • Advanced analysis modeling and superior geometry foundation A modern CAE environment • Multi-discipline simulation and optimization NX CAE directly addresses the challenges you face with sim- • Systems-level simulation ulation today through a modern and completely integrated • HD-PLM for leveraging CAE results to make smarter environment that delivers significant benefits. NX CAE does decisions not require NX CAD and can be used as a standalone pre/ postprocessor with support for multi-CAD geometry. NX CAE delivers additional benefits when used in situations where NX is used for design, such as seamless data transfer SDRC UGS SIEMENS between the design team and analysis team. I-deas NX CAE Speed simulation processes by up to 70 percent Increasing simulation productivity speeds your entire product development cycle so you can bring your products to market faster.

MSC Nastran Increase product quality By more easily simulating real-world conditions, you get a truer understanding of how your product will perform. NX CAE also facilitates easier trade-off analysis across multiple disciplines so you develop more robust products. Requirements tracking and reporting capabilities allow you to quickly gauge if your product is performing to specification 3 Advanced analysis modeling “The NX associated modeling NX CAE drastically reduces the time you 3D meshing and meshing capability repre- spend preparing analysis models.
