anuga.Transmissive_momentum_set_stage_boundary

class anuga.Transmissive_momentum_set_stage_boundary(domain=None, function=None)

Bounday condition object that returns transmissive momentum and sets stage

Returns same momentum conserved quantities as those present in its neighbour volume. Sets stage by specifying a function f of time which may either be a vector function or a scalar function

__init__(domain=None, function=None)

Create boundary condition object.

Parameters:

• domain – domain on which to apply BC

• function – function to set stage

Example: Set all the tagged boundaries to use the

>>> domain = anuga.rectangular_cross_domain(10, 10) 
>>> def waveform(t):
>>>    return sea_level + normalized_amplitude/cosh(t-25)**2
>>> BC = anuga.Transmissive_momentum_set_stage_boundary(domain, waveform)
>>> domain.set_boundary({'left': BC, 'right': BC, 'top': BC, 'bottom': BC})

Methods

__init__([domain, function])	Create boundary condition object.
evaluate(vol_id, edge_id)	Transmissive momentum set stage boundaries return the edge momentum values of the volume they serve.
evaluate_segment([domain, segment_edges])	Evaluate boundary condition at edges of a domain in a list defined by segment_edges
get_boundary_values([t])
get_time()
