NEi Nastran advanced analysisNEi Nastran is the First Leading high level Windows based version of NASTRAN Finite Element Analysis

NEi Nastran design simulation and virtual prototyping products allow companies to reduce product development costs and improve time-to-market. Engineers can determine real-world structural, thermal, fluid-flow, and aero-elastic behavior of both simple and complex 3D product designs. Model generation and analysis time is also reduced by combining powerful and easy-to-use finite element modelers with extremely fast analysis solvers that have a proven record of accurate results.


Advantages & Benefits

Uses the world's leading Windows-based pre- and post-processor for advanced engineering finite
element analysis (NEi Nastran Modeler), which is easy to use and has the power to model very difficult
Comprehensive interactive tools necessary for model creation, analysis monitoring, and results
evaluation including a state-of-the-art analysis
Proven track record demonstrating that NEi Nastran is one of the most trusted products for structural
analysis in all industries.
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
