Features

This solver is capable of coupling Two-Fluid Model with CFD-DEM in a specified region. It is possible to choose between one-way coupling and two-way coupling between Two-Fluid Model and CFD-DEM. In case of using two-way coupling methodology user can choose between mass and momentum coupling or solely momentum coupling between Two-Fluid Model and CFD-DEM. The Two-Fluid Model solver is based on "twoPhaseEulerTurbFoam" and the CFD-DEM simulations are based on CFDEMcoupling and LIGGGHTS developed by Department of Particulate Flow Modelling at Johannes Kepler University in Linz, Austria.

Installation

The OpenFOAM 6, CFDEMcoupling compatible with this solver (CFDEMcoupling-magnificationLens) and LIGGGHTS compatible with this solver (LIGGGHTS-magnificationLens) should already be compiled in your system. Then, download the solver or clone it using git clone. Change the cloned folder name to pfmFOAM. It is very important to load CFDEMcoupling bashrc in a terminal, direct first to inside the CFDEMcoupling folder then,

source etc/bashrc

Then compile turbulencemodels,

cd pfmFOAM/pfm/src/TurbulenceModels
./Allwmake

Then, direct to the pre-processing folder and wmake writeCellGlobalID, writeCellSetLocalIDs, and writePatchFaceGlobalIDsList,

cd pfmFOAM/pfm/applications/utilities/preProcessing/writeCellGlobalID
wmake
cd ..
cd pfmFOAM/pfm/applications/utilities/preProcessing/writeCellSetLocalIDs
wmake
cd ..
cd pfmFOAM/pfm/applications/utilities/preProcessing/writePatchFaceGlobalIDsList
wmake

After compiling the utilities necessary to run magnification solver cases, direct to magnification lens solver folder and compile the solver,

cd pfmFOAM/pfm/applications/solvers/multiphase/MagnificationLensSolver
./Allwmake 

In addition, it is also possible to compile twoPhaseEulerTurbFoam solver which can be used to simulation Two-Fluid Model cases with,

cd pfmFOAM/pfm/applications/solvers/multiphase/twoPhaseEulerTurbFoam
./Allwmake
