This way the algorithm works at its best and creates the most fitting results to the boundary conditions. With this approach it is possible to let the algorithm decide which and how many fixation points are necessary and needed for the applied boundary conditions. The reduction of fixation points almost always results in a more lightweight design by still taking into consideration the Safety Factor/Stress Goal of the structure.

In another other cases, it is important to keep defined fixation points and this can be realized with the activated Keep Non-Design Spaces function.
