Numerical simulation of landslides by coupling fluid-structure interaction

Описание: This is a validation case for high fidelity fluid-structure modelling by Dr. Pan Yang.

Min. ms_f: 0.1m
Max. ms_f: 5.0m

Fluid domain: 164m*60m
ms_s:0.25m
dt_s: 2e-6s

The code is the couple of Fluidity-Multiphase and FEMDEM-Y2D, both developed in Applied Modelling Computation Group (AMCG) at Imperial College London. For details about our open-source code, please refer to http://www.imperial.ac.uk/earth-scien... and GitHub repositories.

The fantastic adaptive mesh is implemented in Fluidity, which is an open source, general purpose, multiphase computational fluid dynamics code capable of numerically solving the Navier-Stokes equation and accompanying field equations on arbitrary unstructured finite element meshes in one, two and three dimensions. It is parallelised using MPI and is capable of scaling to many thousands of processors. Other innovative and novel features include the use of anisotropic adaptive mesh technology, and a user-friendly GUI and a Python interface which can be used to calculate diagnostic fields, set prescribed fields or set user-defined boundary conditions.
