SimcenterTM Optistruct® is a Siemens product
Simcenter Optistruct delivers far more than structural analysis. With over 30 years of continuous development, it has evolved into a robust multiphysics and multidisciplinary simulation and optimization platform, covering both implicit and explicit analysis. When engineers adopt the One Model, One Solver philosophy, the benefits become immediately evident: streamlined workflows, comprehensive analysis capabilities, and faster results — all without sacrificing accuracy.
True optimization goes beyond improving a single design parameter. It requires evaluating every physical behavior of a product and refining the entire system inside one integrated environment. Simcenter Optistruct makes this level of innovation not only possible, but efficient.
Traditionally, engineers have had to rely on multiple CAE tools and separate models to analyze different physical phenomena. With Simcenter Optistruct, they can perform a wide range of multiphysics studies using a single model. The platform seamlessly combines structural and multiphysics analysis, connecting implicit and explicit solvers to support durability, heat transfer, acoustics, fatigue, and more — accelerating development and time to market.
Switching tools and converting models often disrupts productivity. With its open architecture, Simcenter Optistruct allows engineers to incorporate third-party code, customize features, and integrate with leading CAE technologies — all while maintaining the One Model, One Solver workflow. Collaboration and feature extension become smooth and efficient across software ecosystems.
Renowned for its optimization capabilities, Simcenter Optistruct supports lightweighting, structural refinement, multi-model and nonparametric shape optimization, and advanced multi-material topology studies. Engineers can optimize designs for stiffness, strength, weight, manufacturability, composite materials, lattice structures, fatigue performance, sustainability, and more. This advanced multi attribute framework enables rapid iteration, design space exploration, and better decision-making throughout product development.
Evaluate, optimize, and validate designs using linear and nonlinear solvers for stiffness, strength, dynamics, vibrations, acoustics, fatigue, heat transfer, FSI, electric potential, electrostatics, and more.
Analyze complex material behavior — including composites, lattice structures, and nonlinear materials such as viscoelastic, elastoplastic, and hyperelastic — with direct integration to Simcenter Material Data Center or user defined materials.
Assess vibrations, frequency response, acoustics, and NVH performance. Utilize cutting-edge solvers such as AMSES (automated multilevel substructuring eigenvalue solver) and FASTFR for fast frequency response assessments.
Benefit from advanced nonlinear capabilities including modern contact algorithms, bolt and gasket modeling, elastic plastic / hyperelastic / viscoelastic / viscoplastic material models, and large deformation analysis.
Perform drop tests, crash simulations, impacts, damage assessments, erosion, and material behavior beyond the elastic range.
Simulate thermomechanical phenomena, fluid structure and electromagnetic structure coupling, and integrate with manufacturing process simulation to model real world product performance.

CASE STUDY
Multibody simulation is integral to engineering, enabling precise analysis of structural loads and dynamic behaviours in complex systems. In the context of forklifts, where tyres play a critical role due to the absence of suspension systems, accurate tyre modelling is essential. This study develops and validates a hysteretic Bouc-Wen model for the radial dynamics of solid rubber tyres to enhance simulation reliability.
