Hi all,
I have successfully simulated a few CFD-DEM coupling cases with fixed fluid boundaries. Recently, I am very insterested in how to set up a movable boundary of CFD part. For example, during the derformation of DEM particles, I also want to make the fluid boundaries change with the DEM boundaries. When I use Gmsh to generate the CFD boundaries, I found it cannot be changed during the simulations. Could anyone please share me any clues? Thanks ahead!
Best,
Rachel
