OptiStruct enables simulation of the behavior of complex components and systems through a comprehensive set of capabilities, covering both linear and nonlinear domains. You can perform static and dynamic analyses, vibration, acoustics, fatigue, heat transfer, and multiphysics interactions.
At the core of these capabilities lies a modern, proprietary formulation for nonlinear analysis, alongside an optimized NASTRAN-based kernel for linear analysis, ensuring both robustness and accuracy. The platform is engineered to take full advantage of hardware resources, including both CPU and GPU, enabling reduced computation times and high performance, even for large-scale models.

One of OptiStruct’s key strengths is its ability to support the entire structural optimization process directly within the FEM environment.
From topology to shape optimization, including multi-material and multi-model configurations, OptiStruct empowers engineers to design lighter, higher-performing components while reducing cost and development time. Proprietary technologies include fail-safe topology optimization, which ensures robustness under failure conditions, and multi-material optimization, ideal for leveraging the full potential of composites and advanced materials.
Thanks to configurable manufacturing constraints, optimized designs are production-ready, whether for traditional manufacturing processes or additive manufacturing (3D printing).

Unlike other solvers, OptiStruct allows engineers to manage multiple design objectives simultaneously within a single FEM model. For example, it’s possible to evaluate structural stiffness, vibrational behavior, and fatigue life in parallel, without resorting to simplifications or separate models.
This approach minimizes repetitive tasks, improves consistency across analysis phases, and delivers more reliable, meaningful results. The integrated workflow accelerates development and enables more informed design decisions from the earliest project stages.

With its advanced simulation capabilities, scalability across modern architectures, and one of the most powerful optimization engines in the industry, OptiStruct is a comprehensive platform for intelligent innovation.
Whether you’re aiming to reduce weight, validate fatigue life, or optimize structures for new manufacturing processes, OptiStruct provides the tools needed to successfully meet the challenges of modern engineering design.
