NEi Nastran
provides a wide range of industry-proven solutions for manufacturing
applications and material processing that enable our customers to
evaluate and optimize many performance and reliability aspects of
their designs and manufacturing processes. Benefits include: greater
innovation, process automation, shorter development cycles, design
for durability, and reduced physical prototypes.NEi Nastran customers in manufacturing routinely address issues related to:
- Structural durability and fatigue analysis of farming, forestry, construction, and recreational equipment
- Design and analysis of consumer products, washing machines, appliances
- Dynamic analysis of rotating machinery, such as pumps, motors, and compressors
- Thermo-mechanical and fatigue analysis of power generation equipment, such as boilers, turbines, and heat exchangers
- Design of reliable rollover and falling object protective systems (ROPS and FOPS)
- Crash analysis of rolling stock, such as locomotives and wagons
- Static and dynamic analysis of piping systems under various loads, such as thermal, pressure, seismic, and loads
- Life predictions of various mechanisms, such as transmissions and industrial brakes and clutches
- Manufacturing of thermoplastic and polymeric materials
NEi Nastran product suite key benefits for manufacturing processing:
- 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, heat transfer elements, and dissimilar mesh interpolation elements
- High performance processing including advanced parallel PCG 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 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
- Substructuring and Model Reduction allows the creation and reuse of substructures to improve the efficiency of large analyses and provides a convenient method to transfer model data to subcontractors
- Submodeling allows 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
- Multiple subcase capability provides a highly efficient technique to evaluate the response of structures to many different load cases and boundary conditions
- Extensive composite material support including, 2D orthotropic, 3D orthotropic, general anisotropic, laminate lay-up definitions, and a wide range of failure criteria
- 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
- 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
