I am trying to create a simulation with polyhedra, spheres, and facet. The
facets are a stationary geometry generated using ymport.stl(). Materials are:
matSpheres = O.materials.append(ViscElMat(
young=1.0e8,
frictionAngle=radians(fAng),
density=2160,
poisson=0.3,
tc = tcIn,
))
matPoly = PolyhedraMat(
young=1.0e8,
frictionAngle=radians(fAng),
density=2160,
poisson=0.3,
)
matWalls = O.materials.append(ViscElMat(
young=1.0e8,
poisson=0.3,
frictionAngle=radians(fAng),
tc = tcIn,
))
I tried the following engines:
InsertionSortCollider([Bo1_Polyhedra_Aabb(),Bo1_Sphere_Aabb(),Bo1_Facet_Aabb()],verletDist=(2.0e-3),label='collider',ompThreads=1),
InteractionLoop(
[Ig2_Sphere_Sphere_ScGeom(), Ig2_Facet_Sphere_ScGeom(),
Ig2_Sphere_Polyhedra_ScGeom(), Ig2_Facet_Polyhedra_PolyhedraGeom(),
Ig2_Polyhedra_Polyhedra_PolyhedraGeom()],
[Ip2_FrictMat_FrictMat_MindlinPhys(en=0.3, gamma=0.4,
krot=0.3), Ip2_FrictMat_PolyhedraMat_FrictPhys()],
[Law2_ScGeom_MindlinPhys_Mindlin(includeMoment=True,
includeAdhesion=False), Law2_ScGeom_FrictPhys_CundallStrack()],
),
yadedaily says: "python3.7:
/builds/yade-dev/trunk/deb/yadedaily/pkg/dem/FrictPhys.cpp:19: virtual void
yade::Ip2_FrictMat_FrictMat_FrictPhys::go(const
boost::shared_ptr<yade::Material>&, const boost::shared_ptr<yade::Material>&,
const boost::shared_ptr<yade::Interaction>&): Assertion
`dynamic_cast<GenericSpheresContact*>(interaction->geom.get())' failed.
Aborted"
yade says: "FATAL
/build/yade-KdQLrC/yade-2019.01a/pkg/common/InteractionLoop.cpp:143 action:
None of given Law2 functors can handle interaction #1716+4252, types
geom:PolyhedraGeom=10 and phys:FrictPhys=3 (LawDispatcher::getFunctor2D
returned empty functor)"
so I suppose I need a different Law2 but I have tried a number of them and do
not see one that works. Can Yade simulate a mix of spheres and polys with
adhesion between all particles and surface and with rotating resistance on the
spheres? If so, what combination of materials and interactions does one use?
