    Hi there. Have you introduce Chemical Reactions? Is possible including moving meshing on it?

      Introducing heterogeneous catalytic reactions is one of the most recent challenges in CFD-DEM. Unfortunately this simulation is only to evaluate the flow pattern.
      With OpenFOAM, you can actually introduce the moving mesh, independent on the DEM mesh, which is only used to find contacts.
      I never did a CFD-DEM simulation with a fluid moving mesh, I am sure that is actually feasible, at least with a 1 way coupling. In some cases, i.e. a rotating drum without baffles, you can make the drum rotate, solid side, and implement a BC on the fluid to implement the wall shear.

    Hi, are you will to share the case files? I am trying to redo the open foam tutorial of the cyclone in CFD-dem but I hit the limit for particles and I am not sure how to start the fluid simulation first and then add the particles.

      It is quite a long time since I ran those simulations. You can try to use the keyword start value in the insert fix (www.cfdem.com/media/DEM/docu/fix_insert_stream.html) if you want no particles for the first part of the simulation.

    Which solver/tutorial did you use to achieve this simulation???

    • @tonialessi8694

      PISO solver for incompressible fluids

      Thank you for the response. There are 4 piso solvers for incompressible fluids in the CFDEM project. Did you use cfdemSolverPiso solver?
