<p>Topology optimization determines the optimized material distribution
in a given space for achieving an optimized design. Based on the external
loads and boundary conditions, <span class = "ph">Tosca Structure.topology</span>
determines the optimum material distribution in the design space. The
topology optimization creates holes and perforations that extensively
alter the shape of the component. Alternatively, an existing component
can be optimized where the topology optimization rearranges the material
distribution of the component.</p>
<p>The available design space must exist as a FE model. The resolution
of the designed structures depends strongly on the selected discretization.
A fine mesh produces a structure with a higher resolution than a coarse
mesh. On the other hand, it will also substantially increase the processing
time required. A compromise between structural resolution and processing
time needs to be found.</p>
