Hi Karol,
Thank you very much for your reply.
I've tried to use this function to block DoFs. But it didn't work.
This is part of my code. The clump's DoFs weren't blocked.
OutDiameter=0.1143
PipeRoughR=0.01
SectionNum=20
LongNum=15
WidthX=0.6
HeightZ=3
HeightZ0=0.3
thickness=0.01
gravity=(0,0,-10)
densityPipe=7850
InputR=OutDiameter/2-PipeRoughR
Gap=sin(pi/SectionNum)*2*InputR
LengthY=Gap*(LongNum-1)+PipeRoughR
PipeParticleNum=0
PP=[]
for j in range(LongNum):
for i in range(SectionNum):
PipeParticleNum += 1
PP.append(sphere([InputR*sin(i*2*pi/SectionNum)+0.3,j*Gap,InputR*cos(i*2*pi/SectionNum)+0.3],radius=PipeRoughR,,color=(1,1,0)))
PPID=O.bodies.appendClumped(PP)
PPClump=O.bodies[PPID[0]]
PPClump.dynamic=1
PPClump.state.blockDOFs='xyXYZ'
PPClump.state.vel = (0, 1,0)
PPClump.state.angVel = (0,0,0)
h=0.4

sp.makeCloud((thickness*5,0.001,h),(WidthX-
thickness*5,LengthY-0.001,h+.2),rMean=0.02)
