about: Surface Miner Simulation and Analysis with Altair EDEM and Altair OptiStruct
Hello everyone,
I hope this message finds you well. I am currently working on a FEM-DEM coupled model using EDEM and SIMLAB, specifically following the procedures outlined in provided examples, such as the surface miner simulation. However, I have encountered a few questions that I am struggling to find answers to, and I would greatly appreciate any assistance.
Firstly, can anyone confirm whether the volume packing type of factory can be utilized in the SIMLAB-EDEM coupling process? When I implement volume packing, it seems that the entire defined displacement control load is applied at the beginning of the simulation. Consequently, this gives the impression that the analysis in SIMLAB functions as a static analysis rather than an explicit dynamic one. I also reviewed the example deck file for the surface miner simulation, but I noticed that the factory is missing from the EDEM deck file.
Could someone please clarify the limitations or issues related to using volume packing in coupled analyses? I am aware that it works with MotionView-EDEM simulations. For reference, I am using the 2024 version installed on our university server.
Thank you in advance for your support!
