anuga.Inlet_operator

class anuga.Inlet_operator(domain, region, Q=0.0, velocity=None, zero_velocity=False, default=0.0, description=None, label=None, logging=False, verbose=False)

Inlet Operator - add water to an inlet. Sets up the geometry of problem

Inherit from this class (and overwrite discharge_routine method for specific subclasses)

Input: domain, Two points

__init__(domain, region, Q=0.0, velocity=None, zero_velocity=False, default=0.0, description=None, label=None, logging=False, verbose=False)

Inlet Operator - add water to a domain via an inlet.

Parameters:

• domain – Specify domain

• region – Apply Inlet flow over a region (which can be a Region, Polygon or line)

• Q – function(t) or scalar discharge (m^3/s)

• velocity – Optional [u,v] to set velocity of applied discharge

• zero_velocity – If set to True, velocity of inlet region set to 0

• default – If outside time domain of the Q function, use this default discharge

• description – Describe the Inlet_operator

• label – Give Inlet_operator a label (name)

• verbose – Provide verbose output

Example:

>>> inflow_region  = anuga.Region(domain, center=[0.0,0.0], radius=1.0)
>>> inflow = anuga.Inlet_operator(domain, inflow_region, Q = lambda t : 1 + 0.5*math.sin(t/60))
