Structural analysis is the process of evaluating how physical structures respond to forces, loads, and environmental conditions. It helps engineers predict performance, identify potential failure points, and optimise designs before physical testing.

Simcenter™ 3D integrates advanced structural simulation capabilities into a unified CAE environment, enabling engineers to virtually investigate product performance under a wide range of operating conditions—including thermal, dynamic, and nonlinear scenarios. Powered by Simcenter Nastran®, it supports everything from basic linear statics to complex multistep nonlinear analyses, offering scalable solutions for both general and specialist users.

Including simulation in the development cycle, when previously only physical tests were performed, is advantageous, especially when using Simcenter 3D. There are many cost and time advantages since you can validate the structural performance earlier in the design cycle to identify potential issues, avoiding costly physical builds. In some cases, when physical sensors can not be placed or the desired location cannot be reached, simulation can provide data that would otherwise be unattainable.

Furthermore, simulation can be scaled to test various scenarios, materials, and geometries quickly, where parameters can be adjusted easily and tests rerun. In comparison, physical tests would require much more time to rebuild and reconfigure the hardware.

Deadicated structural analysis software, such as Simcenter™ 3D, have been produced for structural simulation. Simcenter 3D integrates a wide range of analysis types—linear statics, fatigue, nonlinear dynamics—into a single user interface. This eliminates the need for multiple tools and streamlines workflows for engineers

Powered by Simcenter Nastran® it offers scalable finite element solvers for everything from small components to large industrial models. It can support linear analysis, normal modes, harmonic response, transient dynamics, and aeroelastic flutter and is available on laptops, workstations, and servers; compatible with Windows and Linux.

Efficient structural simulation, especially for complex structural analysis or detailed stress analysis, often requires robust hardware. High-performance CPUs, ample RAM, and powerful GPUs significantly reduce computation times. Investing in suitable resources ensures smoother workflows and faster turnaround for intricate structural simulation projects.

To ensure integration across engineering and design teams, tools like Teamcenter provide centralised access to simulation data, analysis artifacts, and finite element models.

Structural simulation software provides highly accurate predictions when properly applied. Validation against experimental data or analytical solutions is crucial to ensure reliable stress analysis and structural analysis results. Understanding model assumptions and limitations is key to achieving trustworthy structural simulation outcomes for design decisions.

Modern structural simulation software aims for user-friendliness, but a foundational understanding of engineering mechanics is essential. Intuitive interfaces and comprehensive tutorials facilitate efficient structural analysis and stress analysis workflows, accelerating proficiency. Initial training helps engineers quickly master the software for effective structural simulation.

Most structural simulation software supports static, dynamic, thermal, and fatigue analysis. Advanced capabilities include non-linear stress analysis, buckling, and multi-physics. This breadth allows engineers to comprehensively evaluate component and system behavior under various loading conditions, enhancing overall structural analysis and design validation.

Seamless integration with CAD is a major advantage, streamlining the structural analysis workflow. This allows direct import of geometries, reducing errors and saving time. Bidirectional links facilitate design iterations and rapid stress analysis updates, making the structural simulation process more agile and efficient.

Interpreting structural simulation results requires engineering judgment. Focus on stress concentrations, deflections, and safety factors. Post-processing tools visualize data, but understanding assumptions and material behavior is critical for accurate structural analysis. Correlate numerical findings with expected physical responses for reliable stress analysis outcomes.
