Two-phase shallow granular flow model
Spreading of a solid-fluid granular mass
Initial conditions: cylinder of height =1, with non-uniform
solid volume fraction described by a Gaussian function.
Inter-phase drag forces and bottom friction are taken into account.
height h
solid volume fraction
The computational model uses
Clawpack libraries.
