OpenLB’s free surface implementation follows the approach of Thürey “Physically based Animation of Free Surface Flows with the Lattice Boltzmann Method”. PhD thesis. 2007.
I am not very familiar with the free energy model so I can’t comment on the combinability. Possibly some of my colleagues will be able to help.
The examples as they are included in the release were tested successfully on various systems – to investigate this problem I’ll need to know more about where and how you tried to execute the simulation and whether you changed anything.
