Customer Feedback

"After years of experience using the MSC package, I was able to migrate over to the NEi Software, Inc. solution with ease. I found their personnel to be more knowledgeable and responsive than my time spent with the MSC hotline. All in all, NEi Nastran offers a better product for thousands less."

Dr. Edward M. Weinstein
Technical Director

NEi Nastran provides analysis and simulation solutions for:

NEi Nastran product suite key benefits:

  • 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 and dissimilar mesh interpolation elements as well as advanced tension only shell and cable elements
  • Specialized solution sequences including Design Dynamic Analysis Method (DDAM), integration with Anteon's Underwater Shock Analysis (USA) program, and compatibility with MAESTRO from Proteus Engineering
  • 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 all tightly integrated with Femap
  • Special modal filtering and database restart tools for performing DDAM and dynamic response solutions increase productivity by allowing a modal database to be altered and reused with rerunning an eigenvalue extraction analysis
  • 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 Modal 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
  • Inertia relief capability allows the quasi-static simulation of forces acting on an unconstrained structure such as aircraft in flight or a submerged submarine
  • Multiple sub case 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
