Re: [Anuga-user] Unable to simulate Rainfall and Tide together

Hi MURUGESH PRABHU,


That sounds a little curious.


Perhaps you can provide you script so that we can see if there is any obvious problem.


Could it be that the runoff from the rain is "overpowering" the tide?


Cheers

Steve

Subject: [Anuga-user] Unable to simulate Rainfall and Tide together

Hi,

I tried simulating rainfall and tide together. Rainfall was supplied using the rate operator and tide was supplied as boundary condition along selected edges.

TIDE:

Bc = anuga.Time_boundary(domain=domain,function=lambda t: [(0<t<3600)*2, 0, 0])

Bc was assigned to coastal boundary edges

RAINFALL:

Q = Quantity(domain, name='rain', register=True)
domain.set_quantity('rain', filename='Rain.asc', location="centroids") # Rain.asc is the rainfall raster file
rain_opertor = anuga.Rate_operator(domain, rate=Q, factor=1.0, default_rate=0.0)

RESULT:

The effect of Rainfall is visible in the output, but tide is not visible.

If I remove the rain, then tide is simulated.

Kindly advise.
