3.3. Assessment

The user can monitor optimization results both while it is running and when it has finished.

If you were not able to run the Multi-objective optimization you can load the project for the post-processing from:
.../modeFRONTIER30x/doc/html/caeInt/FLUENT/u-tube/prj_full/FLUENT.prj

Once we move to the Design Space tab we enter into the post-processing environment.
On the left we find a new tool bar where there are all post-processing tools for result assessment.

Clich on the Design Table icon to show the complete result database (Input and Output Variables, Objective and Constraints), see Fig. 1.
This table updates while the optimization is running and each design is written as soon as it is calculated.

When the optimization has finished we can mark the design belonging to the Pareto Frontier selecting the action Edit > Mark > Mark Pareto Design > only Real from the Edit menu.

Note:Two designs belong to the Pareto frontier, it means that all the other designs are not better of these two for both objectives.

Optimization goals are the flow uniformity obj_uniform_flow and the pressure loss obj_prex; probably this two objectives are in contrast (it means that if one improves the other decreases its preformance).
Create a scatter chart to relate the two objectives. To see the scatter plot of flow uniformity versus pressure loss click on the icon and select obj_uniform_flow and obj_prex among Objectives, see Fig. 2.
