Structural Analysis

Integrated Structural Analysis Solutions Powered by NX Nastran

Understanding how a component or product assembly reacts under stress or vibration is critical in any industry, but as products and materials become increasingly complex, engineers need tools that go beyond linear statics and dynamics analyses.

NX for Simulation includes solutions for a wide range of structural analysis problems within a single user environment. Engineers no longer need one tool for linear statics, another to study fatigue, and yet another for nonlinear analysis. As a result, engineering departments can consolidate analysis tools, and engineers only need to know a single user interface. NX structural analysis software is powered by NX Nastran, the premier FEA solver for computational performance, accuracy, reliability and scalability. The NX Nastran solver is integrated within the NX CAE enviornment, or it can also be used as a standalone enterprise solver. NX CAE also supports structural analysis solutions from other commercial finite element solvers, such as Ansys, Abaqus, and LS-Dyna.

Linear Analysis

Liinear Analysis

Solve a broad range of analysis problems where materials are not strained beyond linear behavior, and where deformations remain small in relation to overall dimensions.
