Forum Post: RE: Calculation Options
You need to select the calculation type as per the analysis you want to perform E.g. if you want to perform age analysis then you have to select age as the calculation option. If you are selecting...

Mohsen, " per capita " basically means per person. The Population Unit field in the Unit Demands manager just lets you select a unit to associate with your unit demand, for labeling purposes. So, if...

For the first question, I think you're saying that the number of leakage nodes shown at the top part of the solution is 9, but you see more than 9 entries in the list of adjustments at the bottom? The...

Hi Jesse I got it. Thank you. Then working with model, the total demand of a special Junction will be sum of 'Demand Collection' & 'Unit Demand Collection' (both are under 'Demand' tab in...

Nine is generally too high for the number of leakage node. I'd suggest 1 to 3. With 9, the solver slows down as the decision space gets very large and you can end up with a lot of false positives. You...

Yes, if you've only entered regular demands in the Demand Collection and unit demands in the Unit Demand collection, the total demand for a junction (as seen in the calculated Demand field) is the sum...
