Modelling of a Screw Fixation

Opportunity 1:

A screw fixation can be modelled by using a nondesign Nondesign space (red) around the screw which is fixed in all directionsas a shell. The Nondesign space is constrained using a clamped fixation.

Opportunity 2:

To simulate the reality it is also possible to load in an extra volume that’s representing the screw.

However, keep in mind that the screw becomes part of the Design space, so you need the original space without the screw to create a good intersection with the optimization results. Further information regarding the intersection here.

The screw (blue) will be used as a fixation and is considered fixed in all directionsclamped. Additionally, there should be a nondesign space around the screw (red), which will be is included in the design space as well, but which will not be used as a fixation in the optimization model. This way the nondesign space does not experience an artificial stiffening, which represents the reality much more accurately.
