[TRNSYS-users] Solar Domestic Hot Water system error-a negative flow

[Ying Yu]

hi,

I was doing simulation in TRNSYS for a Solar Domestic HOt Water system, and the file (in the attachment) generates 1 fatal error- a negative flow encountered, and there is no detail information in the Lst file for debugging purpose.

I have tried different global timesteps (1s, 1 min, 10 min), but same error occurs at time 2898hr (simulation is starts at 2880 ends at 2904 hr).

Any help would be great appreciated.

Best regards,
Ying Yu
