Which parameters should I set to fix the fatal error in the "PDA" mode?

[LittleBrize]

When I use the latest version of owa-epanet to run the hydraulic analysis in the mode of PDA, I encountered a fatal error about pump simulation.

The network contains many leak nodes, which are modelled by emitters. Pumps are used to lift the water in the upstream tank to the downside. The initial status of pumps is OPEN. There are no any control rules for them. During the EPS, the upstream tank is empty, whereas the value of the flow for pumps are positive.

When I use the EPANET 2.2 GUI to run the same network, there are no errors. That is, the flowrate of pump is zero. They are switched closed.

I do not know how to set parameters for this error.
