anuga.Kinematic_viscosity_operator

class anuga.Kinematic_viscosity_operator(domain, diffusivity='height', use_triangle_areas=True, add_safety=False, verbose=False)

Class for setting up structures and matrices for kinematic viscosity differential operator using centroid values.

As an anuga operator, when the __call__ method is called one step of the parabolic step is applied. In particular the x and y velocities are updated using

du/dt = div( h grad u ) dv/dt = div( h grad v )
