<p>The initial model is illustrated in the following figure. The boundary elements of the left
holes are fixed, and the inner nodes of the rightmost hole are loaded in the
Y-direction.</p>
<p><br/><img class = "image" src = "../TsoExampleImages/topoSensGroupOperModel.png" width = "378"/><br/></p>
<p>All elements of the model are part of the optimization except for the elements with loads
or boundary conditions.</p>
<p>The maximum displacement of all nodes of the loaded hole is to be constraint.</p>
