the coupling of openlb and DEM does not exclude the usage of partially saturated methods (PSM) as proposed by . In fact, in  we compared different fluid-solid interface approaches to study the Galilean invariance for vortex-induced vibrations with OpenLB including different PSM approaches. A collision, based on a weighting of the collision operators according to , can be included into your code by using the PSMBGKdynamics in the latest release of OpenLB (v1.3 – 1).
