CFDEMInterFoamIB
A CFDEM solver to simulate the interaction between two-phase fluid and granualr materials
- Before installing this solver, ensure that the CFDEM+LIGGGHTS+OpenFOAM are correctly installed.
**A Chinese tutorial to install the CFDEM+LIGGGHTS+OpenFOAM:
如何安装CFDEM+OpenFOAM+LIGGGHTS(COOL三件套)
- To install this solver, you just need to run the "remake" file after you successfully installed the previous codes.
Introduction to tutorial cases
- single_sphere
This case is used to show the interaction between particle and two-pase phase in the settling process. Phenomena such as the cavity, splashing, and back-jet can be observed.
- Multi_sphere_fish
This case is an application of using the DEM clump. A clump consists 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"):
Notice: this animation has a time period of 0.8 s. In the tutorial case "single_sphere", only 0.01 s is set (tutorial/single_sphere/CFD/system/controlDict line 26: endTime 0.01) just for the validation of successful installation. The user should change the endtime into 0.8 s to get the same result as the above animation.
Fish settling (corresponds to the tutorial case "multi_sphere_fish"):

Notice:
This solver is still on an early release. Questions about installing, compiling, and tutorials cases will be further replied.
Update logs
2023-05-11:
A case named "multi_sphere_fish" is added in the tutorial. This case can help the users to use the clump DEM model in coupling.
