Summary
Optimization workflow
Analysis of results
The model is a metal sheet with hole.
The sheet is fixed constrainedalong the bottom edge
Two distributed loads along top and right sides are applied
Model Definition
top and right sides are applied
Model parameters are: Position, dimension and
fillet of the hole Thickness of the metal
sheet
Model Parameterization
Structural Analysis
The mesh is automatically created by Workbench
The distributed loads are applied on two side surfaces (100 N)
Optimization Workflow (modeFRONTIER)
Design ParametersInput variables 5 geometric variables
Output variables Maximum stress and
displacement Mass
Design goals Minimize maximum
displacement Minimize mass
Optimizations set-up dataSampling phase: Original configuration nr initial
individuals: 16
Exploration phase: MOGA-II scheduler 320
iterations
Optimization Analysis Parallel Chart
The Parallel Chart allows the filter of the designs in order to get the
optimal values for both the objectives
The set of Best Designs (Pareto frontier) can be visualized
Displacement is inversely correlated with mass
Displacement is
Optimization Analysis Correlation Chart
Displacement is inversely proportional to thickness
Mass is directly proportional to thickness
