Hi all,
I'm simulating the CPT tests. I use the geom.facetCylinder and geom.facetCone
commands to generate the penetrator.
the code shows below:
#############################################################
x0=0.2;y0=0.2;z0=0.39665
cylinderIDS= O.bodies.append(geom.facetCylinder((x0,y0,0.35665),
radius=0.0125,height=0.15,orientation=Quaternion((1, 0, 0),
0),wallMask=5,segmentsNumber=10, angleRange=None,material=facetMat))
coneIDS= O.bodies.append(geom.facetCone((x0,y0,0.270825),
radiusTop=0.0125,radiusBottom=0.0,height=0.02165,orientation=Quaternion((1, 0,
0), 0),wallMask=6,segmentsNumber=10, angleRange=None,material=facetMat))
#######################################
I did two tests. one is 10 segments number, another one is 50 segments number
for the cylinder and cone.
###############################
for the 10 segments case: the simulation runs without particles blowing up.
while for the 50 segments case, the particles blowing up after the penetrator
touches the sample surface.
#########################################
These two simulations are exactly the same except for the segment number. for
these two cases, I set the same timestep.
#######################################################
GlobalStiffnessTimeStepper(active=1,timeStepUpdateInterval=10,timestepSafetyCoefficient=0.8),
###################
###################
I think the particles blowing up may result from the time step.
Do you have any advice?
Thanks!
