Question #665514 on Yade changed:
Status: Open => Answered
Bruno Chareyre proposed the following answer:
You are right overall on the need to bound with boxes in current PFV
implementation. It does not mean that the box has to be entirely filled. What
it enables directly is the simulation of a submerged avalanche. For an
avalanche exposed to air there could be ways to impose appropriate pressure
boundary conditions to the elements filling the empty part of the box, this is
Alternatively, if you go for periodic boundary conditions you can have a x-y
aligned chute with inclined gravity, which makes the free surface condition
easier to impose.
2/ LBM: I don't think it is a realistic option
3/ TwoPhaseFlow: irrelevant
4/ A possible option you did not mention is HydroForceEngine [a], it is
probably more realistic than 2/ and 3/
I hope it helps.
