I'm using 'hydraulic pressurized tank' component in my hydraulic system model
Sometimes, 'Flow rate at port 2 is negative' warning message has popped up
Actually, flow rate at port 2 is positive, not negative
Well, even if a warning has popped up,
Check the 'Continuation run' option in 'Run parameter' and redo the simulation,
Simulation is working again.
This warning message appeared frequently.
I don't know why this error occurred
and, How can I handle it
Is it some kind of bug? in LMS Amesim?
Solved! Go to Solution.
can you try to activate the "discontinuities printout" option in the run parameters and start a new simulation?
Then when the error occurs, can you update your plot?
This would allow to add missing points showing us what happens.
To prevent from possible negative flows at the tank intlet, just put a check-valve at the inlet.
Production: Amesim 14.1, Autonomie R12
I activate the 'discontinuities printout' option and set 'print interval' vale to 0.001
but, I can not find missing point
figure. activate the 'discontinuities printout' option
Following your advice, I added a check-valve component
After that 'Flow rate is negative' error is not occuring
But a new error -'Tank is empty'- is occuring, even if the tank is not empty
Ok , I'll check the initialization values of my system model, thx
