After you set up your design run, click Compute 
to compute the results of your design.
After you have computed your design run, Solutions is added to the hydraulic model list.
| Solution |
The list of solutions |
| Fitness |
Fitness is the overall score given a solution by Darwin Designer. For Minimize Cost solutions, a lower fitness is best. Otherwise, higher fitness indicates the best solution. |
| Total Benefit |
This only has a value for Maximize Benefit and Multi-Objective Trade-off calculations. This is a score of the calculated benefits, with a higher value indicating more benefit in terms of improved network pressure. |
| Total Cost |
Total Cost displays the sum of rehabilitation and design costs. |
