Reply To: HLBM: particle-particle interaction and fluid-particle momentum exchange
Dear Junwei Guo,
after intruducing HLBM to OpenLB in 2017 there have been various minor, but also some major changes, including the momentum exchange algorithm. A lot of them are documented in a more recent publication on HLBM and the OpenLB user guide. You are strongly advised to contemplate both. Another more up-to-date publication is being worked on at the moment, however no specific date for it can be given for now. Here, some further changes to the algorithm will be discussed, which will eventually be part of our next release, which is scheduled for the end of this very month. In case you are looking for the greatest consistency between publications and the implementation, you might need to await the upcoming release and our next HLBM related publication. Another option is of course to attend our next OpenLB spring school, which will give you the opportunity to talk with the developers directly.
I hope, this is of any help for now.
Best,
Nicolas
