> the time step
The PWaveTimeStep is 1.02e-08.
By the way, the default option of Yade is in parallel and uses all of the
available cores? In the tutorial, it says, "By default, each job uses all
available cores for itself, which causes jobs to be effectively run in
parallel. Number of cores per job can be globally changed via the --job-threads
option"
If i just start a job by "yade pyname.py", is it executed in parallel and
uses the available cores? If so, how many cores does it use when i start a new
job without designating the cores to use? To grab some cores from the first
job?
> the meaning of the mass reduction
For my case, the packing density is an important factor to affect the
following process. Larger mass makes denser packing. So this is the meaning of
the step. Yes. I agree with you the mass modification changes the physical
process. But if we actually care about the random feature of particle packing
not the exact the particle distribution.
Thanks,
Xuesong
