At an early stage of planning, I do not yet have any indication of the hydraulic conditions in the network and therefore cannot yet design any precise circulation pumps. How can I then define the required conditions of the models (‘PelFile’ in the Pump model)?

In the ‘Pump’ model, you have the option of removing the calculation of the auxiliary energy quantities via the ‘usePowerCalc’ parameter by setting it to ‘false’. This input is then no longer necessary and the connector to the grid model is no longer visible.
