Jan Stránský proposed the following answer: Hello Jessica, it may depend on particle radius in certain sense.. you can estimate the time of the simulation like this: totalTime = numberOfSteps * computationTimeOfOneStep numberOfSteps can be determined (in your case) from strain rate and timeStep dt ( numberOfSteps = finalStrain / (strainRate * dt) ) dt is dependent on mass, stiffness and size of your particles (see e.g. [1]). computationTimeOfOneStep is dependent on number of particles (approximately N*log(N) ) and power of your computer. Usually it is not difficult to measure it (do not measure the very first step as it is O(N^2) due to the collider's first sorting of particle positions). So if you know computation time for certain number of particles, you can estimate computation time for different number of particles. You can try to use these formulas to estimate the time of your simulation and it should not *dramatically* differ from reality. hope I wrote it in understandable way :-) cheers Jan [1] https://yade- dem.org/doc/yade.utils.html#yade.utils.SpherePWaveTimeStep -- 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 : [email protected] Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
