Altair OptiStruct

OptiStruct 10.0 New Feature Highlights

• Concept design synthesis and design fine-tuning can be carried out based on fatigue performance.
  
• Damage and life from either stress-life or strain-life fatigue analysis can be used as design criterion.
  
• Computationally efficient compared to fatigue-based optimization using 3rd party applications.

• Innovative method that enables optimization of both flexible bodies and rigid bodies
  
• First in the market to do system level concept design and optimization
  
• Allows free-size, topography, size, free-shape, shape and material design variables in the optimization study

• Acoustic pressure can be used a design criteria in optimizing vehicle NVH characteristics

• Temperatures from heat transfer analysis and structural responses can be used to optimize a coupled thermo-mechanical system.

• Responses to non-deterministic, probabilistic loading in the form of PSD or RMS values can be used as design criteria.

• Enables matching of a set of design responses to a corresponding set of defined target values

• Surface-to-surface input allows easier modeling than CGAP elements
  
• FREEZE option allows modeling of tied interfaces for static, normal models, and other linear analysis types

• SPMD version for multiple static, linear buckling, direct frequency response load cases
  
• Iterative solver for static solution
