Improvement Suggestion – Graph Preservation (or transfer) When Merging Openflow WaterGEMS Models

• When merging or combining two OpenFlows WaterGEMS models, hydraulic elements such as pipes, junctions, pumps, tanks, and valves can be transferred successfully into the destination model.

• However, graph definitions created in the source model are not preserved or transferred during the merging process.

• Graphs are commonly used to analyse simulation results such as pressure, flow, tank levels, and pump performance.

• In many modelling projects, especially large systems or multi-zone models, a significant number of graphs are created for analysis and reporting.

• Currently, users must recreate these graphs manually after merging models, even though the referenced elements already exist in the destination model.

• It would be beneficial if WaterGEMS could provide a feature to preserve, transfer, or import graph definitions during model merging.

• This enhancement would improve modelling efficiency and reduce repetitive work, particularly for large or complex hydraulic models.
