CFDEMInterFoamIB

A resolved CFD-DEM coupling solver for two-phase fluid interaction with particles

1. Before installing this solver, ensure that the CFDEM+LIGGGHTS+OpenFOAM are correctly installed.
   A Chinese tutorial to install the CFDEM+LIGGGHTS+OpenFOAM:
   How to install CFDEM+OpenFOAM+LIGGGHTS: Chinese version
2. To install this solver, you just need to run the "remake" file after you successfully installed the previous codes.

WSL environment setup

For step-by-step installation and compilation in WSL, see the Chinese WSL setup guide.

Introduction to tutorial cases

1. single_sphere
   This case is used to show the interaction between particle and two-phase fluid in the settling process. Phenomena such as the cavity, splashing, and back-jet can be observed.
2. multi_sphere_fish
   This case is an application of using the DEM clump. A clump consisting of overlapping sub-spheres is constructed to represent a fish-shaped object. Users should learn how to do multi-sphere modeling in LIGGGHTS.

Animations of some cases:

Sphere settling (corresponds to the tutorial case "single_sphere"):

For the current simulation settings and run procedure, see the single-sphere tutorial guide.

Fish settling (corresponds to the tutorial case "multi_sphere_fish"):

Notice:

This solver is still on an early release. Questions about installation, compilation, and tutorial cases are welcome.

Changelog

2023-05-11: A case named "multi_sphere_fish" is added in the tutorial. This case can help users learn how to use the clump DEM model in coupling.
