Xue is still having a problem:
Hello jan!
I rechecked the shape of the two particles in the above interaction. As you
expected, the contact is not a combination of spherical particles + polyhedral
particles.
The above model is a coupling model built with oofem and yade, the id=3841 in
the error report exceeds the number of particles I imported via yade, so I
deduce that this should be a transformed unit (facet?) on the coupling
interface. Therefore, the contact type should be polyhedral particles +
transformed unit from FEM.
However, I did not figure out where the contact parameters of the interface
unit are defined when it is involved in the contact force calculation (in DEM)?
Besides, the above reported error only appears when I defined FrictMat in the
script. When I define only PolyhedraMat and use only the following engine, the
problem did not occur.
O.engines =[
ForceResetter(),
InsertionSortCollider([Bo1_Sphere_Aabb(),Bo1_Facet_Aabb(),Bo1_Polyhedra_Aabb()],verletDist=.0005),
InteractionLoop(
[Ig2_Sphere_Sphere_ScGeom(),Ig2_Facet_Sphere_ScGeom(),Ig2_Facet_Polyhedra_PolyhedraGeom(),Ig2_Polyhedra_Polyhedra_PolyhedraGeom(),Ig2_Sphere_Polyhedra_ScGeom()],
[Ip2_FrictMat_FrictMat_FrictPhys(),Ip2_PolyhedraMat_PolyhedraMat_PolyhedraPhys()],
[Law2_ScGeom_FrictPhys_CundallStrack(),Law2_PolyhedraGeom_PolyhedraPhys_Volumetric()],
),
NewtonIntegrator(damping=0.7,gravity=(0,0,-0.3),label='newton'),
]
I apologize for providing wrong information.
