It's a good performance for that number of particles and the corresponding number of interactions gouing in hand with that for a compression test. Btw.: here is the link[2] from above which I could not paste in here as wiki was down: https://yade-dem.org/wiki/Multicore_Performance I'll complete it step by step.

I have read Yade's documents and the Question #222363 from Henry. Despite I have known that the relationship between micro-parameters Kn, Ks and macro-parameters E,P can be described as: Kn=2.*E*R1*E*R2/(E*R1+E*R2) (1) Ks/Kn=P (2) these can not solve my problem completely because that in my simulation, Kn and Ks are unchanged in different contacts. How can I do to achieve this.

E and P refer to material parameters young and poisson, but they ar NOT the same as macroscopic Young's modulus and Poisson's ratio. Furthermore, from your question I could not really understand what your problem is. Could you please be more clear? thanks Jan 2013/5/7 Fu zuoguang question222...@answers.launchpad.net Question #222363 on Yade changed: https://answers.launchpad.net/yade/+question/222363 Fu zuoguang posted a new comment: Dear all: Thanks for helping me last time and I have some questions about the Parameters about Kn and Ks.

Re: [Yade-users] [Question #228175]: Accelerate the simulation with CUDA
Question #228175 on Yade changed: https://answers.launchpad.net/yade/+question/228175 Bruno Chareyre proposed the following answer: I'm afraid that such number of calculation timesteps is necessary because the stress-strain curve didn't reach a steady state yet. The question is how you define the timestep (is it already the largest acceptable dt for stability?) and if some parameters could be tweaked to let larger dt be used. Typically, if you are interested in the steady state, it doesn't really matter if the stiffness is a bit less... -- You received this question notification because you are a member of yade-users, which is an answer contact for Yade. ___ Mailing list: https://launchpad.net/~yade-users Post to : yade-users@lists.launchpad.net Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
