Problem

After computing a model that contains manholes with sanitary loads, the result field "Flow (System Sanitary)" reports no flow for all elements.

Solution

This will happen if the Extreme Flow Cutoff is set to 0. The Cutoff Value is the maximum possible extreme flow factor (EFF) for peaking methods. This is used to prevent unrealistically high values for small populations or land areas. For a reference, the Harmon Equation extreme flow in the delivered engineering library has this value set to 5.
