lingran posted a new comment: Hi Bruno, Thanks for your answers. They do help me a lot. I am interest in dynamic energy conservation issues. I am dealing with impact of a boulder onto a soil layer. In order to investigate impact mechanisms, the soil layer is divided into different parts. Energy transmission and dissipation inside each soil layer supposes to be tracked, and before doing that, the total energy should be balanced. For your comments, I did several tests and found that the errors do decrease with time step. When simply conducting gravity deposit, a sample of 2000 particles, without friction and moments, the error is about 0.03%. But when dealing with impact problems, consider friction (use O.energy[‘plastDissip’]) and moments, the error sometimes could be as high as 3~10%, in addition, the error depends on the size of the whole sample, the number of particles, impact energy, time step, etc. Thanks.
