Moving geometries in DEM/CFD-DEM #543

Closed DanW97 closed 2 years ago

DanW97 commented 2 years ago

Hi,

Is it possible for user-created geometries (e.g. an agitator) to interact with DEM particles in either DEM or CFD-DEM simulations? I can see from the docs that I can define parameters for a wall, but nothing about how to define additional geometries. I'm interested in using Lethe for a stirred mill, so, ideally I would like the stirrer to be able to move and interact with the DEM particles.

Cheers,

Dan

Dear Dan, For the DEM component, moving geometries have been added something like 3-4 days ago. The documentation is in an open PR. https://github.com/lethe-cfd/lethe/pull/547 For unresolved CFD-DEM, this will be coming this year. For Resolved CFD-DEM, it should be not too difficult also, but we have not yet ironed out the kinks of it.

These are projects that would not be necessarily that difficult to work on as starter project and I'd be glad to help you integrate the moving geometries for DEM into the unresolved solver.

Hope that helps!

Best Bruno
