Optimization

Successive Response Surface Method (SRSM)

• Very effective algorithm for highly nonlinear problems such as crashworthiness or metal forming applications

Genetic Optimization Algorithm (GA)

• suitable for arbitrary problems in particular for complex performance functions
  (e.g. many local minima)

Multidisciplinary Optimization (MDO)

• More than one load case and more than one CAE-Discipline
  Parallel execution of multiple load cases with different analyzing types and possibly different variable definitions
• Discipline-specific job control
• Discipline specific point selection schemes (experimental design)

Multi-Objective Optimization

• Simultaneous optimization of more than one objective function
• Pareto Front Solutions

Reliability Based Design Optimization (RBDO)

• Optimization that directly accounts for the variability and the probability of failure

Robust Design Optimization (RDO)

• Optimizing design and robustness simultaneously

Optimization variables

• Continuous and discrete variables
• Mixed discrete-continuous optimization
• Dependent (linked) variables

Identification of system-/material parameters

• Calibration of models to experimental data

Shape optimization

• Process of optimizing the geometrical dimensions of a structural part
  Interface to parametric pre-processors: ANSA, HyperMorph, TrueGrid, User-Defined

Examples: 

• Crashworthiness Optimization
• RBDO
• Coupling Ansa
