Hello all

I am trying to simulate a landslide. I will generate spheres and materials between the balls, but I do not know how to generate materials between spheres and face.The last line of code error, I don't know how to write.Please help me.

This is the code 

################################
from yade import pack
import gts, os.path, locale


#-----------------------Creat materials----------------------
O.materials.append( CohFrictMat( young=1E8,poisson=0.35,density=2100,frictionAngle=radians(30),normalCohesion=2e4,shearCohesion=2e4,momentRotationLaw=True,label='cMat' ) ) # material to create the gridConnections
O.materials.append( FrictMat( young=9E8,poisson=0.38,density=2100,frictionAngle=radians(22),label='fMat' ) ) # material for general interactions


#------------------Create spheres and facet-----------------
surf=gts.read(open('2222.gts'))
surf1=gts.read(open('1111.gts'))
if surf.is_closed():
	pred=pack.inGtsSurface(surf)
	aabb=pred.aabb()
	dim0=aabb[1][0]-aabb[0][0]; radius=dim0/100. # get some characteristic dimension, use it for radius
	O.bodies.append(pack.regularHexa(pred,radius=radius,gap=0,material='cMat'))
	for b in O.bodies:
   		b.shape.color = (0,191/255.,1)
O.bodies.append(pack.gtsSurface2Facets(surf1),wire=False,material='fMat')

Looking forward to your answers
Appreciate
