Supporting Generative Design


Designer Oriented Topology Optimization

Designer oriented topology optimization• Tool used by designers• Operate directly on CAD geometry• Meshless (to the user)• Optimize for linear static loads• Returns new smooth CAD geometry with optimal configuration


Topology Optimization in the Design Environment

Powerful optimization tools forthe designer

• Work on a single part or in an assemblycontext

• Specify realistic manufacturing constraints

• Output geometry directly to AdditiveManufacturing / 3D printing

• Complete topology optimization process ina very short time


Analyst Oriented Topology Optimization

Analyst oriented topology optimization• Tool used by analysts• Operate on FE geometry• Nastran based optimization allowing to use all traditional Nastran

elements (beams, solids, bars…)• Optimize for static loads, mode frequencies, dynamic loads, buckling

loads ….• Define where Lattice structures can be used• Returns new smooth FE model with optimal configuration – validate the

design• Returns new smooth CAD geometry with optimal configuration

CFD Based Topology and Shape Optimization

CFD Based topology optimization• Tool is part of Star CCM+• Tool is mainly used by Analysts• Operate on FE geometry• Optimize for CFD based objectives (swirl, pressure drop uniformity

index …)• Returns a facetted surface that encapsulates the optimum flow channel

Convergent Modeling

Create Convergent Bodies frompolygon geometry

• Easily transfer CAE geometry back todesign

• Enable designer to incorporate changesresulting from CAE studies

• Leverage Reverse Engineering toolset inModeling for Convergent Body operations


Convergent Modeling

Bring legacy mesh data to life

• Automatically convert meshes into polygonfaces and bodies

• Rapid creation of new geometry for orphanmeshes

• Make design changes using Modeling toolsand update the mesh


Design with Convergent Modeling

Modify generative models by adding precise geometryCombine facets with

precise geometry

Prismatic features Freeform features

For visible parts that requiregenerative design, you needsome human influence on theshape, finish for aesthetics,brand recognition etc.


Convergent Modeling™ in CAE

Edit facet models as if they weregeometry

Breathe life into legacy mesh data to turn it intoeditable geometry

Make design changes using Modeling tools andupdate the mesh

Quickly refine results from Topology Optimization

Edit scan data as if it were real geometry, thenquickly mesh and simulate for fast verification
