NEi Nastran is a powerful, professional level, finite element analysis tool relied on by major industry groups to simulate and analyze linear and nonlinear stress, dynamics, and heat transfer characteristics of structures and mechanical components, including composites. Integrated tightly with FEMAP.
NEi Nastran FEA Software product suite key benefits
* Comprehensive interactive tools necessary for model creation, analysis monitoring, and results evaluation including a state-of-the-art analysis Editor.
* Uses the world's leading Windows-based pre- and post-processor for advanced engineering finite element analysis, FEMAP Modeler, which is easy to use and has the power to model very difficult analyses.
* Pre- and post-processor integrated with multiple industry-standard structural and thermal solvers.
* Specialized industry-proven element technologies, including hybrid quad and hex elements, advanced tension-only shell and cable elements, surface and spot weld elements, dissimilar mesh interpolation elements, and heat transfer elements.
* High performance processing including advanced parallel PCGLSS iterative, sparse direct, and block Lanczos solvers which allow solutions to large-scale models over 10 million degrees of freedom on inexpensive 32-bit Windows workstations with support for even larger model sizes on high end 64-bit Linux workstations.
* 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.
* Robust contact capability using a 3D surface contact method which easily handles dissimilar meshes between components including frictional effects.
* Extensive composite material support including 2D orthotropic, 3D orthotropic, general anisotropic, laminate lay-up definitions, and a wide range of failure criteria.
* Basic through advanced material models including temperature dependent materials, nonlinear elasticity and plasticity effects, creep and thermo-elasticity.
* Multiple subcase capability provides a highly efficient technique to evaluate the response of structures to many different load cases and boundary conditions.
* Substructuring and model reduction allows the creation and reuse of substructures to improve the efficiency of large analyses, provides a convenient method to transfer model data to subcontractors, and allows in-depth evaluation of particular regions and convenient transfer of models to subcontractors.
* 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.
* Submodeling allows in-depth evaluation of particular regions.
* Support for standard manufacturing process effects such as casting induced warpage, residual stress and strain.
* Inertia relief capability allows the quasi-static simulation of forces acting on an unconstrained structure such as aircraft in flight or a submerged submarine.
* Advanced modeling capability features robust CAD import, advanced beam modeling, mid-surface extraction, hex and tet meshing, and a broad range of loads, materials, analyses types, and visualization options.
* Used to model virtually anything including aircraft, satellites, marine vessels, heavy construction equipment, and medical devices by engineering organizations and consultants world-wide.
* Integration with specialized fatigue applications such as Winlife, which is available as an add-on to the NEi Nastran product suite and also fe-safe, nCode, Falancs, and FE-Fatigue.
* Proven track record demonstrating that NEi Nastran is one of the most trusted products for structural analysis in all industries.
