Dear Researchers,
Do you know any papers giving implementation details/algorithm of the Immersed Moving Boundary scheme (Proposed by Noble 1998) which is commonly used in the coupled Discrete Element Method and Lattice Boltzmann Method? Thanks
I have done a bunch of work with this technique, the papers by Feng, Owen and Leonardi, are the best descriptions of the algorithm. For example: http://onlinelibrary.wiley.com/doi/10.1002/nme.2114/full
I also explored at length how to compute quickly the intersection volume between DEM particles and the LBM grid. This is an expensive part of the coupling, and you can get a 100x speed up if you use the approach I describe here:

Article Fast computation of accurate sphere-cube intersection volume
Thank you! Bruce.
I wanna some papers with specific details of the IMB implementation rather than basic theory. Such as the fast searching method for different nodes. Prof Feng and I have proposed two algorithm about searching nodes. Now we want to know how other researchers do it. Thanks
Ah great! I would be interested in reading about your approach. You may want to search for authors coupling DEM to finite volume or finite difference since the process is very similar.
