01
Linear Analysis
NX Nastran features a complete range of linear analysis including static problems, transient problems where loads change over time, buckling load capacities and heat transfer behavior.
02
Advanced Nonlinear Analysis
When deformations are large, linear assumptions invalid, or contact is a factor, nonlinear analysis is the appropriate choice. NX Nastran supports implicit and explicit solvers for problems ranging from plastic catches to car body roof crush.
03
Rotor Dynamic Analysis
Rotating systems like shafts and turbines are subject to gyroscopic and centrifugal forces. Rotor dynamic analysis allows engineers to predict critical speeds and develop designs that operate safely away from unstable speeds.
04
Computational Performance
Shared Memory Parallel (SMP) and Distributed Memory Parallel (DMP) processing enable significantly faster solutions for today's complex models with tens of millions of node points and elements.
05
Ease of Modeling
Connectivity features including linear contact, glue connections for dissimilar meshes, bolt preloading, and thermal expansion for rigid elements simplify the modeling process and save time.
06
Integration with NX CAE and Femap
NX Nastran is deeply integrated with NX CAE and Femap software tools. Solver and graphics teams work closely together ensuring enhancements are rapidly supported by corresponding advances.
