Dear Bruno Chareyre:
Thanks for helping me last time and now I am trying to understand all the
details of algorithms in O.engine class in Yade just for very basic simulations
with DEM and then list all of them. These tasks have not been finished
recently. Today my question is about PSD task in Yade.
In yade, particles generation with a given PSD can be done by these
sentences :
##################################################################################
sp0 = pack.SpherePack();
sp0.spmakeCloud(mncorner,mxcorner,num,psdSizes,psdCumm,distributeMass=True)
O.bodies.append([sphere(center and rad in sp0,particles_mat)])
##################################################################################
# psdSizes: sieve sizes for determine particle sizes in test.
# psdCumm: cummulative percentage numbers from 0~100%.
Two questions:
(1).There are two methods for psdCumm, one is based on mass cummulation and the
other is based on
number cummulation. I think both of the two can be done in
Yade(distributeMass=True or False) but don not know the algorithm and the
tranfer relationship between the two.
(2).If I choose (distributeMass=False), can the cummulation mode be transfered
from 'mass' to 'number'?
Seeking your help!
