Description:

System seems to hang at this step, but eventually shows the error;

Hydraulic Calculation - The system flow demand of ####.## exceeds the maximum rated flow as indicated in the Pump Curve for the pump with the inlet of PI and outlet of PO.

The calculation will not continue Calculation failed for an unknown reason

May not be 1a.3 or 2.3, could be anywhere along here.

Solutions:

Cause:

Possible the pump is legitimately too small

Solution:

Insert a larger pump, just to get the Autocalc to run through, then edit the water supply as necessary once you get into the calculation file. [GAB 3/01/19]

Cause:

If it seems that the flow requirement is MUCH more than what seems normal, it's likely the user broke the pipe between the nodes PO & PI in the drawing and had another pipe leading out to the source.

Solution:

This must be one solid pipe between the nodes PO & PI. You need all the pipe connected between the flowing sprinklers and the last point where your water supply is set up.
