SIMULIA TOSCA STRUCTURE
THE STRUCTURAL OPTIMIZATION SYSTEM
TOSCA STRUCTURE
KEY BENEFITS
TOSCA STRUCTURE ADVANCED CAPABILITIES
Full optimization potential with realistic simulation models
Nonlinear analysis—exploit the benefi ts of topology, sizing, shape and bead optimization in combination with contact,
material nonlinearity and large deformation. Avoid error-prone and time consuming model simplifi cation.
Reduced weight and ensured reliability
Durability—augmenting shape optimization using fatigue simulation results, with standard or in-house fatigue solvers.
Save weight and ensure highest result quality for reliable components.
Faster design decisions by quickly changing mesh geometry
Morph—extending shape optimization to enable fast and easy creation of design variants. Make geometry changes
directly applied to the existing fi nite element mesh and avoid intermediate CAD modifi cations.
TOSCA STRUCTURE FEATURES
Innovative, lightweight design concepts
Topology optimization
Conceptual design for lighter and stiffer structures. Create
lightweight, ready-to-manufacture product designs and
reduce time-to-market, physical tests, and prototype
builds.
Improved designs for more durability and strength
Shape optimization
Improve existing designs for more reliable and durable
components. Minimize stress, strain, and damage – or any
combination of these – by automatic modifi cation of the
surface geometry.
Effi cient bead patterns for increased stiffness
and reduced noise
Bead optimization
Improve the static and dynamic properties of shell
structures. Generate optimal bead layouts while
accounting for manufacturing constraints, complex
geometries, and realistic loads.
SIMULIA Tosca Structure is a fl exible, modular software system for non-parametric structural optimization that provides topology,
sizing, shape and bead optimization optimization using industry standard fi nite element solvers (ANSYS, Abaqus, MSC Nastran).
The setup is simple – model parameterization is not necessary. Existing solver input fi les are used for the optimization. Tosca
Structure is based on market-leading technology and provides advanced capabilities for optimization with nonlinear analysis and
fatigue as well as a specifi c non-parametric morphing approach.
Best static and dynamic behavior through
optimized sheet thicknesses
Sizing optimization
Obtain an optimal relation between weight, stiffness,
and dynamic behavior, to gain material savings and take
advantage of increased comfort.
Wind turbine mainframe
Optimization with Tosca Structure.topology
For larger wind turbines stiffness and strength requirements are
more diffi cult to meet. The redesign of the mainframe should
result in an economic design with optimal vibration behavior.
Topology optimization of the mainframe led to a lightweight
structure which met static and dynamic criteria. Manufacturing
constraints were considered during the optimization to
generate a producible design, e.g. to avoid under-cuts. Mass
reduction approaching 40%, a feasible fi nal design, and a faster
development process were achieved.
Rear wheel carrier
Optimization with Tosca Structure.shape
For the weight optimization of the chassis component multiple
criteria such as strength, fatigue, plasticity and stiffness had to
be considered.
Violated stiffness demands required a modifi ed design for the
rear wheel carrier considering damage requirements for multiple
loads and maximum allowed strain for breaking loads. With
Tosca Structure a shape optimization was performed directly on
the existing model without error-prone model simplifi cation or
time consuming parameterization. After 20 automated analysis
steps a redesign was derived with better performance and even a
reduced mass compared to the initial design.
Automotive muffl er
Optimization with Tosca Structure.bead
Noise issues motivate engineers to fi nd the optimal dynamic
behavior of the muffl er. Key quality factors such as structural
stiffness and vibration behavior should be met.
In order to reduce noise and improve structural stiffness, bead
patterns are formed in sheet metal structures. In an automatic
loop with Tosca Structure.bead the optimal bead layout was
achieved after only three fi nite element analyses. Manufacturing
requirements were directly applied to achieve a faster
turnaround from analysis to the production process.
Body-in-White
Optimization with Tosca Structure.sizing
A higher eco-effi ciency is one of the main targets in the
automotive industry. To realize a signifi cant weight reduction
of a body-in-white, the optimum balance between weight,
stiffness, and dynamic behavior is required.
Targeting weight reductions, Tosca Structure.sizing optimizes
sheet thicknesses clustered together in groups or individually, up
to element level. This way the best static and dynamic behavior
for a body-in-white can be found. Through consideration of
multiple complex load scenarios, stiffness, and manufacturing
requirements, Tosca Structure.sizing helps to meet performance
and production goals for an overall increase in eco-effi ciency.

The integration of Tosca Structure into the product
development process resulted in a shorter time-to-market
for the mainframe, and a lightweight cast structure with
40% mass reduction.
Damage was reduced by 60% from the initial value. At the
same time formerly violated stiffness constraints were met.
EXAMPLES OF INDUSTRIAL USE OF TOSCA STRUCTURE
After only three FE analyses, a bead layout was created using
Tosca Structure. The 1st and 2nd eigenfrequencies were
increased signifi cantly—from 280 to 520 Hz, and from 340
to 570 Hz, respectively. A corresponding reduction of noise
was achieved.
The optimal combination of weight, stiffness, and dynamic behavior
using Tosca Structure.sizing resulted in a weight reduction of
15%—from initial 329 kg to 280 kg. While high stiffness
requirements contribute to an increase in comfort, all other
performance goals are met within a reduced development time.
