I am encountering small amount of flows in dead end pipes. I filtered my pipes by selecting all pipes that have flows smaller then 0 so that i could find all the negative flows. and what i noticed was there were still some values that were equal to 0 after filtering. So I changed units and formatting to 10 decimal place and found that these values were not 0 but had a very small amount of flow. This is confusoing since these pipes are all dead end pipes with no customer meters / demands attributed to them. Is there a explanation for this?
The solution algorithm uses a numerical solution which means it is stopping at some reasonable accuracy. Any values past the second (or so depending on the units) decimal place are just noise and should be ignored.
