The described example uses the following model: (Design elements are shown in blue, the elements in red are defined as nondesign elements due to loads and boundary conditions.)
The optimization target is to minimize the maximum von Mises stress with a volume constraint of 30%:
The following diagram shows the difference between the maximum elemental centroidal von Mises stress calculated by the FE solver and the stress interpolated by SIMULIA Tosca Structure:
