Coupling recommendations between OpenLB and DEM software

Hello everyone!
I’m new to Lattice Boltzmann Methods (LBM) and currently working on modeling particle-bubble collisions in water. My plan is to implement this using an **LBM-IBM-DEM** (Lattice Boltzmann Method – Immersed Boundary Method – Discrete Element Method) coupled approach.During my research, I explored both Palabos and OpenLB as potential frameworks. However, I noticed that Palabos’ coupling modules for DEM haven’t been updated in eight years, which makes them less practical for modern implementations.
**My questions are:**
1. Are there better approaches for this specific particle-bubble interaction scenario?
2. Can OpenLB be integrated with other DEM software packages (e.g., LIGGGHTS or Yade)?Any insights or recommendations would be greatly appreciated!
Best regards!1/ If you aim at resolved simulations (resolved particles and bubbles), I would go for phase field and HLBM resolved particles.
2/ Can be done in OpenLB without any external tools, since in OpenLB there is DEM (point particle and resolved particles with HLBM). Coubling with other tools are possible but in general not really efficient, esspiecially using CPU/GPU clusters!
