TriaxialStressController on a cloud of particles without contact, in a fluid

Asked by Rioual on 2019-03-22

Hello,

Is it possible to use "TriaxialStressController" on a packing of particles which have initially no contacts (a cloud of particles) in
 a viscous fluid (described by the DEM PFV coupling as in the example oedemeter.py) ??

Thank you for your views,

Fr.

Hi, yes, it makes no difference for the fluid solver if particles are in
contact or not.
There is less validation of the local hydraulic conductivity model for very
dilute suspensions, but it will give a result anyway.
