2.2. Geometry meshing<br />
Figure 2: Original shape<br />
Figure 3: Optimized shape<br />
In the next design step, the 3D-shape had to be transferred into a structural grid. Due to the<br />
complex geometry a simple projection method could not be used in this case. Standardized<br />
methods and tools do not exist for this task. Often, automatic mesh generators from FEanalysis-<br />
or 3D modelling software are used. However, they usually do not lead to<br />
satisfying results. <strong>The</strong>se meshing tools start from the boundaries and connect separately<br />
generated zones, which leads to irregular meshes in the centre. This isn’t satisfying from<br />
neither an aesthetical nor structural point of view. Figure 4<br />
