HEC-RAS 2D Error

[Anonymous]

I have a major problem during a 2D Unsteady Flow simulation.
The data which I use are the followings:
-Terrain
-2DFlowArea
-Mannings jpeg
-BC Lines
-Dam
In unstedy flow i use precipitation for boundary

povod?: Mesh property tables are current.

Anyone any suggestion?

I need some help regarding adding the precipitation in the HEC-RAS.

1- What does the actual mean of time series of precipitation? Is it mean the accumulated rainfall?
for example

Date Simulation time Precipitation (mm)
11-01-2019 07:00 00:00 30
11-01-2019 08:00 01:00 30
11-01-2019 09:00 02:00 30

Does it mean the total rainfall added on the 2D flow area during the whole simulation time is 90 mm? Please elaborate?

Thanks
