How to couple Ansys WB with ModeFrontier Optimizer
Citation preview
• Model definition and Parameterization
• Structural analysis
• Optimization workflow
Summary
• Optimization workflow
• Analysis of results
• The model is a metal sheet with
hole.
• The sheet is fixed constrained
along 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 Parameters
Input variables
• 5 geometric variables
Output variables
• Maximum stress and displacement
• Mass
Design goals
• Minimize maximum displacement
• Minimize mass
Optimization’s set-up data
Sampling 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

Optimization Analysis – Bubble Chart
• The Bubble plot shown is a 4D view of
the scatter
• It compares the design that have been
investigated with respect to different
objectives
