is a modular system for nonparametric structural optimization. Topology,
shape, bead, and sizing optimization of FE models can be performed with 
<span class = "ph">Tosca Structure</span>
for the design of lightweight, rigid, and durable components and systems. A
parameterization of the model is not needed.
</span>
 
<p> Topology optimization determines an optimum design proposal starting
with a given maximum design domain. </p> 
<p> In Shape optimization, the components surface is modified to reduce
local stress or damage peaks. </p> 
<p>Bead optimization is used to determine the optimum location and
orientation of bead stiffeners for sheet metal components. With 
<span class = "ph">Tosca Structure.bead</span>,
the static stiffness and the vibration behavior can be improved. </p> 
<p> Sizing optimization derives optimal thicknesses for a shell structure
to, for example, increase stiffness or reduce vibrations. </p> 
<p> Structural optimization with 
<span class = "ph">Tosca Structure</span>
is an iterative process. The structural response of the component is calculated
in each design cycle with an external FE solver. The user can work with his
favorite solver in his favorite pre- and post-processing environment and does
not need additional training in a new CAE environment. </p> 
<p> A closed development process can be achieved by the interaction of the
components of 
<span class = "ph">Tosca Structure</span>
from the first concept to the optimized geometry in the CAD system. </p>
