Hello everybody,

I am new in YADE and I am trying to have a depositions of cylinderConnections by adding each cylinderConnection one by one using PyRunner.  Somehow the cylinderConnections lose the connection with the nodes and stop the evolution in time, but the nodes keep the evolution. *The CylinderConnections start elongating from the position they stopped.

This is the functions I am using

PyRunner(command = 'createRandomCylinder()', virtPeriod = 1.0, label = 'cylinders')

this is the function :

def createRandomCylinder():

	global nodesIds
	global cylIds
	global vertices

	Nc		= 9		# number of fibers
	rFib	= 0.2	# radious of the fiber
	Ne		= 20	# nymber of nodes for the fiber
	dx		= 0.0   # distance between two fibers X
	dy		= 1.0	# distance between two fibers Y
	dz		= 0.0   # distance between two fibers Z
	LFib	= 8.0  	# size of the fiber

	dzj = 2.0*Lz 	#Initial position Z
	dyj = 0.5*Ly  	#Initial position Y
	dxj = 0.5*Lx   	#Initial position X
	omegaY = 20.0 	#Frequency Y
	omegaX = 20.0 	#Frequency X
	phiY = 0.0 	#Desfase Y
	phiX = 0.0 	#Desfase X
	hY = 0.2 	#Amplitud Y
	hX = 0.2 	#Amplitud X

	nodesIdsAux = []
	cylIdsAux = []
	verticesAux = []
	
	for i in range(0, Ne+1):
		pz = float(i)*LFib/float(Ne)
		py = hY*sin(float(i)*omegaX + phiY)
		px = hX*sin(float(i)*omegaY + phiX)
				verticesAux.append([px + dxj,py + dyj, pz + dzj])
	nodesIds.append(nodesIdsAux)
	cylIds.append(cylIdsAux)
	vertices.append(verticesAux)
	cylinderConnection(vertices[-1],rFib,nodesIds[-1],cylIds[-1], wire=False, color=[1,0,0],highlight=False,intMaterial='cylindermat',extMaterial='fMat')

Thank you very much,

Antonio
