Complexity
The Complexity influences the design of the result regarding the degree of detail. The picture below shows the influence the Complexity value has on a design.
The higher the value the more detailed results are created. More Struts are being created but also very thin shell structures.
Tip: Start with a lower value (4-14) for the first optimisation to see where the design takes you. Afterwards increase the value till you get the detailed design you want to reach.
Note: The higher the complexity the longer the calculation takes.
