PerronNLDiffuse

Nonlinear diffusion, following Perron (2011). This module uses Taylor Perron’s implicit (2011) method to solve the nonlinear hillslope diffusion equation across a rectangular, regular grid for a single timestep. Note it works with the mass flux implicitly, and thus does not actually calculate it. Grid must be at least 5x5. Boundary condition handling assumes each edge uses the same BC for each of its nodes. This component cannot yet handle looped boundary conditions, but all others should be fine. This component has KNOWN STABILITY ISSUES which will be resolved in a future release; use at your own risk.

    Nonlinear diffusion, following Perron (2011).

    This module uses Taylor Perron’s implicit (2011) method to solve the nonlinear hillslope diffusion equation across a rectangular, regular grid for a single timestep. Note it works with the mass flux implicitly, and thus does not actually calculate it. Grid must be at least 5x5. Boundary condition handling assumes each edge uses the same BC for each of its nodes. This component cannot yet handle looped boundary conditions, but all others should be fine. This component has KNOWN STABILITY ISSUES which will be resolved in a future release; use at your own risk. The primary method of this class is run_one_step.
