Hello guys, i have a problem with an unsteady flow simulation. I try to change the increment and the number of points in the HTab cross section, i change the computation interval in the computation settings but the model is still unstable. It give me very high vel. in relation to the vel. that i obtain in steady flow simulation. I read on user manual that i can use the flow spatial plot and the flow time series plot to find the problem, or viewing the log file, but i’m novice in this two options. If i open the log file i find this warning:
!WARNING, USED COMPUTED CHANGES IN FLOW AND STAGE AT MINIMUM ERROR. MINIMUM ERROR OCCURRED DURING ITERATION 6.
COMPUTED STAGES AND DISCHARGES AT T = 3.0856 HOURS – 11/22/2019 AT TIME 03:05:08
but i don’t know where find exactly the problem and fix it.
Thank you to all
