Structural Analysis Software | FEA, Nonlinear & Optimization
Structural analysis helps engineers predict how parts and assemblies respond to real loads—stress, deformation, vibration, and failure risk—before anything is built. TrueInsight supports structural workflows across Altair and Siemens Simcenter, from fast CAD-based studies to high-fidelity nonlinear simulation.
Structural Analysis & Simulation
What Is Structural Analysis?
Evaluating Strength, Stability, and Structural Performance
Structural analysis is the practice of evaluating strength, stiffness, stability, and dynamic behavior under expected operating conditions. In product development, it’s commonly performed with finite element analysis (FEA) to identify stress hot spots, excessive deflection, buckling risk, and durability concerns early—reducing prototype loops and helping teams converge faster.

Frequently Asked Questions
To predict stress, deformation, vibration, and failure risk under real loads so designs can be validated before manufacturing.
Linear structural analysis assumes small deformations and proportional material behavior, making it suitable for many standard engineering problems. Nonlinear analysis accounts for large deformations, contact, plasticity, and material nonlinearities, which are required for complex or highly loaded structures.
Most structural simulations require meshing to divide geometry into finite elements. However, some modern tools use adaptive meshing or meshless techniques that simplify the setup while still delivering accurate results.
Crash and impact simulations typically require explicit dynamic solvers such as Radioss or LS-DYNA. These tools can accurately simulate high-speed impacts, material failure, and complex contact behavior.
Structural analysis is widely used in automotive, aerospace, civil engineering, energy systems, heavy machinery, and consumer product design to ensure safety, durability, and performance.
Simulation allows engineers to test designs virtually before building physical prototypes. By identifying issues early, teams reduce testing cycles, lower manufacturing costs, and accelerate product development.
