In the live Post Processing, the iterations of the optimisation are displayed as soon as they are available. The current iteration is shown and the number is displayed at the bottom progress bar. Furthermore, the progress bar shows the planned number of iterations. The Design Space can be displayed by selecting the button Initial Shape beneath the progress bar. The optimisation can be aborted by selecting the stop button next to the scenario in the left top corner. After finishing or aborting the optimisation the Post Process can be left with the exit button in the right bottom corner.

The Failure Criterion can be chosen in the studies tab for every optimisation scenario. Dependent on the intention of the optimisation it can be chosen between the equivalent von Mises Stress, a FFF Thumb Rule or directional dependent Tsai-Hill or Tsai-Wu Failure Criteria. More information regarding the Failure Criteria here.
In combination with the Safety Factor and the material properties (material limits) the Failure Criterion is the objective of the optimisation. The target is to load all the material with a value of 1 of the chosen Failure Criterion.

The Optimisation evaluation is displayed in the Optimisation Achievement Index. This shows in which areas the optimisation goal was reached, was exceeded or where there is more potential. So this value gives an indication in which areas the structure will change in the next iteration either by growing or reducing elements regarding to the colour.

Geometry Output
...
, Result Export and Transfer to Model Tree
The buttons in the bottom bar give the opportunity to switch between three different geometries.
...
The Print-Geometry is the Geometry which can be directly manufactured. It includes the extra material from the applied Machining Allowances which can be removed in a precise machining process like milling.
...
STL Export
All of these three geometries can be exported as an a STL-file by selecting the button Export Design Candidate (beneath the progress bar). Because Generative Designs can be very complex, we recommend saving files as Binary-STLs.
...
Transfer Geometry
Furthermore, the displayed geometry can be transferred directly to the model tree. Therefore, the button on the right side can be used. After transferring the Smooth-Geometry to the model tree a NURBS CAD-file can be created. How to do this is described here.
...
Build Direction
If a Build Direction was entered during the model set up it can be visualised in the Post Processing as well. A build direction can be used for Manufacturing Methods like FFF or Metal AM.
...
Result Files
You can find all result files as well as the different log files of the optimisation in your workspace. Per default your workspace is defined as:
