Tutorial: incompressible‐‐pimpleHFDIBFoam‐‐fallingParticleDistribution

Case description

This tutorial represents a situation where a number of non-spherical particles of different sizes is sedimenting in a rectangular domain.

Note that in order for the tutorial to be fast to evaluate even on personal computers, it is constructed as two-dimensional. However, the DEM part of the code is suitable only for three-dimensional simulations and the particles properties were adjusted in such a way that the tutorial gives plausible results.

Running the case

The case is run using ./Allrun script:

`#!/bin/sh
. $WM_PROJECT_DIR/bin/tools/RunFunctions

rm -rf 0

cp -r 0.org 0


runApplication blockMesh     # mesh generation, see system/blockMeshDict

application=`getApplication` # selects application (pimpleHFDIBFoam) from system/controlDict

runApplication $application  # run the simulation itself
