In addition to influencing the design through the Strut Density the results can be altered with different Shape Quality settings. You can decide whether only a "Preview", a "Balanced" or a "manufacture" up to the printable design Fine Tune" optimisation should take place.
In most cases, an a "estimationPreview" only takes a few minutes and gives an overview of the weight and stress development design that an optimization optimisation can achieve under the given boundary conditions. The “estimatation” does not provide a finished design, but only gives you an idea of the development and the possibilities for the optimization. The "optimization" It can be seen where the flow of forces is located and therefore material is needed. Furthermore, it can be checked whether a load/event has been forgotten and if the Design Space is chosen well or the design reaches the Design space limits. This result is not a finished calculation and does not consider the defined stress goal, yet. It is a very fast, first shot at the optimisation and can be used to check the boundary conditions and the ratio of the loads to the stress goal.
The "Balanced" optimisation can take up to a few hours, depending on the conditions Boundary Conditions, number of Events and the Complexity of the model. It provides a detailed/high resolution design proposal and the stress goal of the optimisation is considered fully.
The "ManufactureFine Tune" option takes the longest time , because here the resolution at the end of the optimization is significantly increased and calculates a few more iterations than the Balanced option on the highest resolution level. Because of this it takes quite a bit longer in order to obtain a good printable surface and detailed structure of the component in detail.
An example of the different settings is shown in the following pictures.

result. The surface develops the most in these iterations and a lot of details are changed.
