NEi Nastran product suite key benefits for automotive engineering:
•	Comprehensive interactive tools necessary for model creation, analysis monitoring, and results evaluation including a state-of-the-art analysis editor.
•	Specialized industry-proven element technologies including hybrid quad and hex elements, surface and spot weld elements, and dissimilar mesh interpolation elements.
•	High performance processing including advanced parallel PCG iterative, sparse direct, and block Blanco solvers which allow solutions to large-scale models over 10 million degrees of freedom on inexpensive 32-bit Windows workstations as well as high end 64-bit Linux clusters.
•	Robust contact capability using a 3D surface contact method which easily handles dissimilar meshes between components including frictional effects.
•	Basic through advanced material models including temperature dependent materials, non-linear elasticity and plasticity effects, creep, and thermo-elasticity.
•	Model Reduction and Sub structuring allowing in-depth evaluation of particular regions and convenient transfer of models to subcontractors.
•	Sub modeling allowing in-depth evaluation of particular regions.
•	Load and Boundary Condition Interpolation allows mapping of thermal and CFD output from specialized heat transfer and fluid dynamic models to the structural model for load and boundary condition definition.
•	Advanced solution sequences such as linear and nonlinear static, transient dynamic, steady state dynamic, frequency extraction, heat transfer, and other analysis types, provide a choice of appropriate analysis types for different types of simulations.
•	Support for standard manufacturing process effects such as casting induced warpage and residual stress and strain.
•	Integration with specialized fatigue applications such as Winlife, which is available as an add-on to the Ministrant product suite and also fe-safe, nCode, Falancs and FE-Fatigue.
