Hi Karin, Just to add to Dan's comments...
1. DEME can be simply seen as a general-purpose DEM solver. A recent paper we published that is particularly related to your use case is this <https://arxiv.org/abs/2307.03445>. About its usage see this <https://arxiv.org/abs/2311.04648>. We are looking into the Windows compilation problem and if it is important for you, we can let you know if the problem is resolved. 2. Chrono::FSI can be seen as an SPH solver. So it is really about a different numerical approach to modeling the soil other than DEM: The "fluid" (can be actual fluid or granular material) is modeled with SPH markers and the solid is modeled with BCE particles. Note that I understand in many other domains especially mesh-based simulations, the term FSI puts emphasis on soft deformable structures, but I am not aware of published materials that implement deformable solids with Chrono::FSI. However, there could be new developments concerning SPH interacting with ANCF elements in Chrono that I am not aware of. Anyone feel free to comment. 3. Chrono:GPU can be seen as a monodisperse-only DEM solver. As Dan said, if you wish to capture the soil response accurately with monodisperse DEM particles, you do need to be a bit more creative, such as adding particle cohesion to account for the lack of geometric locking. All of them require you to have a GPU to run. Thank you, Ruochun On Wednesday, November 8, 2023 at 4:35:46 AM UTC-6 Karin Sugi wrote: > Hi, > > Thanks for your support!
