Hi, I also need to do large scale simulation which may need to do around 500,000 for field engineering case. but instead of using YADE I have to develop my own code to do this, :(. In my opinion, the CPU computing time is the most important issue in DEM, while the memory is determined by the total particle number, and you data-structure design, 2GB can do a lot for a 2D case, for 3D case you may need more memory. but the momory requirements will not change much when your total particle number is defined.
hi, Vaclav, is it possible that the 5 mins used for packing or sample preparation to fill the container? I just guess, for my case, it takes some time for this step and then enter the cycling. Wishes.
