Benefits
Accurate and Comprehensive Physics
An inaccurate simulation is one not worth performing. This becomes more important when designs are being driven and optimized based on simulation results. Therefore, at Altair, we strive to develop accurate and comprehensive analysis solutions that capture the behavior of products in the everyday environment that they are developed to exist in.
Highly Parallelized Solver
OptiStruct is a highly parallelized solver that is able to take advantage of the latest hardware technology. Through methods such as domain decomposition, OptiStruct can be executed on hundreds of cores. This has even bigger implications in the larger design development scheme, allowing engineers the ability to perform large scale optimization runs, design for reliability and robustness, and carry out design exploration studies via design of experiments and so on.
Most Advanced Solver for NVH Analysis
OptiStruct supports the most advanced features and process workflows necessary for efficient and effective noise, vibration, harshness and acoustic analyses. Through innovative process workflows, full vehicle NVH analyses can be performed very quickly and efficiently.
Better Performing, Lightweight and Innovative Designs
The strategic use of appropriate optimization technology throughout the design process maximizes the potential for designers and engineers to rapidly develop better performing designs. Through these advanced optimization algorithms in OptiStruct, often, better performance comes along with a reduction in weight through the development of an innovative design concept.
Optimization Enabled Solution
Optimize! Optimize! Optimize! The most efficient way to meet the many, often conflicting and challenging design requirements in a timely and economical manner is through the application of optimization in the design process. Simulation needs to drive the design process. Therefore, the OptiStruct development strategy of enabling analysis solutions for optimization stands out as one of our differentiators, while empowering clients with the best technology to develop the best designs.
20 Year Legacy of Award Winning Optimization Technology
For over 20 years now, OptiStruct has lead the development of new and innovative optimization technology. This includes many first-to-market technologies such as stress and fatigue based topology optimization, topology driven design for 3D printed lattice structures, and technologies for the design and optimization of laminate composite structures among others. OptiStruct provides the most comprehensive library of optimization responses and manufacturing constraints allowing the needed flexibility to formulate the widest range of optimization problems.
Seamless Integration into Existing Processes
Integrated in HyperWorks, OptiStruct can help significantly reduce corporate spending on competitive solver technology. Furthermore, utilizing existing pre- and post-processing environments with superior analysis workflows, OptiStruct can be seamlessly integrated in existing processes with minimum disruption.
Recover Valuable Engineering Time
Simplified and easy to understand error messages, combined with strict model checking contribute to more accurate simulation of design behavior. This allows more time for engineering instead of time spent model debugging as well as iterating due to modeling errors.
Easy to Learn
Using streamlined analysis workflows and the commonly understood Nastran input format, OptiStruct is very easy to learn and to have integrated in to existing processes.
