In the following figure, the initial model is illustrated. The boundary elements of the four lower holes are fixed
and boundary elements of the upper hole experience a force in X-direction.

<br/><img class = "image" src = "../TsoExampleImages/beadBracketPemagDesign.png" width = "378"/><br/></p>
<p>All free nodes of the model (red area in the lower figure) should be used for optimization. The
boundary nodes, which are fixed in the finite element model, should
also be fixed during optimization. Also, the nodes on the outline of the structure should not be changed during optimization.
Therefore, the node fixations of the finite element model are activated for the optimization procedure.</p>
