Hello, My plan is to simulate a slowly evolving granular system, with time scales of days for the frame rendering, and the whole simulation would probably cover several hundreds of days.
Since the DEM time step is usually very low (~1e-5s), I was thinking of scaling down the time. In other words, I would accelerate the process. But I have now several questions: - First, is it the solution you recommend? - Since I really do not want to impact the physics of the phenomena in the system, what should I scale as well? I use material-based properties for the simulation. I guess the gravity would have to be scaled, what about the material properties? - How do I choose the acceleration factor? 1 day could be represented by 1e-5s, 1s, 10s, etc. What kind of criterion is usually used?
