huisky is still having a problem:
Hei,

by issuing help(HydroForceEngine) in Yade, I got following message:

Welcome to Yade 1.07.0

Yade [1]: help(HydroForceEngine) 
---------------------------------------------------------------------------
NameError                                 Traceback (most recent call last)

NameError: name 'HydroForceEngine' is not defined


It obviously is not included in the current release of Yade, is it strange?
I've tried to use Yadedaily and it works!

well, i'm actually want to simulate the buoyancy of the sphere. however,
it seems that all the spheres drop to the bottom anyway due to gravity.
By introducing the hydroforce engine, should the sphere be kind of
floating on the water surface if the density is lower than the water
density?

maybe there are something i'm still missing?

O.engines=[
    ForceResetter(),
    InsertionSortCollider([Bo1_Sphere_Aabb(),Bo1_Facet_Aabb(),Bo1_Wall_Aabb()],label='collider'),
    InteractionLoop(
        [Ig2_Sphere_Sphere_ScGeom(),Ig2_Facet_Sphere_ScGeom(),Ig2_Wall_Sphere_ScGeom()],
        [Ip2_FrictMat_FrictMat_FrictPhys()],
        [Law2_ScGeom_FrictPhys_CundallStrack()],
    ),
    NewtonIntegrator(damping=.1,exactAsphericalRot=True,gravity=(1e-2,1e-2,-10.)),
    TranslationEngine(translationAxis=[1,0,0],velocity=5.0,ids=[id.id for id in strut]),
    HydroForceEngine(densFluid=rau_wat),
]

Liu
