Comments
I know two codes that probably could be added to the list, but I would like an opinion.
OpenFOAM integrates a DEM model. It only implements spherical particles, but it is seamlessly coupled for CFD-DEM simulations. I think that the efficiency is low compared to dedicated codes, but I found it useful. See here: https://github.com/OpenFOAM/OpenFOAM-12/tree/master/src/lagrangian
Also, another module is OpenHFDIB-DEM, an open-source software that couples computational fluid dynamics (CFD) with hybrid fictitious domain immersed boundary method (HFDIB) and discrete element method (DEM). The software is developed as an extension of the OpenFOAM library. See here: https://doi.org/10.1016/j.softx.2024.101871
Thanks for this. Done have been added to the list. I will extend and improve the information on this shortly.
@Lorenzo Pedrolli Can you give me some more details. I could not the DEM solver as part as openFOAM.
Hello @Anthony Thornton , what are you looking for specifically? Since OF is more oriented to fluid simulation, the code structure may be a bit different. OpenFOAM has basic DEM functionality, mainly to support CFD coupling.
This is the main folder that deals with lagrangian types interactions https://github.com/OpenFOAM/OpenFOAM-12/tree/master/src/lagrangian. It contains several implementations including molecular dynamiocs (MD), solidParticles (1-way coupling), and parcel, which contains interacting particles. In there you find the intergration schemes (Euler, analytical) and the various parcel types.
Here, the typoes of parcels are defined. The one we are interested in is collidingParcel: https://github.com/OpenFOAM/OpenFOAM-12/tree/master/src/lagrangian/parcel/parcels/derived. “parcelCloud” defines the particle assemblies, and in “clouds” the types of assemblies are defined, the one we are interested in is “collidingCloud”.
In https://github.com/OpenFOAM/OpenFOAM-12/tree/master/src/lagrangian/parcel/submodels you find the “submodels” implementations, which deal with several types of interactions. In the folder “momentum”, it includes all the sources that can change a particle’s (or parcel) momentum, like “particleForces” you have drag gravity etc. In CollisionModel/PairCollision you find the binary colliison models, either particle-particle or particle-wall: https://github.com/OpenFOAM/OpenFOAM-12/tree/master/src/lagrangian/parcel/submodels/Momentum/CollisionModel/PairCollision. Here you can read the equations for the non-linear SSD model, essentially Hertz-Mindlin: https://github.com/OpenFOAM/OpenFOAM-12/blob/master/src/lagrangian/parcel/submodels/Momentum/CollisionModel/PairCollision/PairModel/PairSpringSliderDashpot/PairSpringSliderDashpot.C
Since version 11, the .org branch reorganised solvers: instead of dedicated DEM solvers, the lagrangian library is fully modular and attached to the standard CFD solvers (pisoFoam, pimpleFoam, etc.), with all particle/parcel handling controlled at run-time. The lagrangian library provides all the methods for domain subdivision (parallel split), neighbour list, particle tracking, interactions, etc.

Here is an open paper on verification / benchmarking with LAMMPS - https://www.sciencedirect.com/science/article/pii/S235234092400221X
Need to integrate this at some point; maybe when we have a page per code.
