I am running the following script to perform a certain test (penetration of a
sphere into an assembly of other spheres). However, I am facing problems saving
the plotted data. My script is as follows:
from yade import pack,plot
import os
pred=pack.inCylinder((0,0,0),(0,0,0.25),0.10)
sp=pack.randomDensePack(pred,radius=0.01,spheresInCell=300)
O.bodies.append(sp)
yade.qt.Controller()
idSteel=O.materials.append(FrictMat(young=210e9,poisson=.25,frictionAngle=.8,label="steel"))
hammer=sphere((0,0,0.30),0.04,material=idSteel)
hammerID=O.bodies.append(hammer)
hammer.state.blockedDOFs='z'
calm()
hammer.state.vel=Vector3(0,0,-0.5)
O.engines=[ForceResetter(),InsertionSortCollider([Bo1_Sphere_Aabb()]),InteractionLoop([Ig2_Sphere_Sphere_ScGeom()],[Ip2_FrictMat_FrictMat_FrictPhys()],[Law2_ScGeom_FrictPhys_CundallStrack()]),NewtonIntegrator(),PyRunner(iterPeriod=100,command="addPlotData()")]
def addPlotData():
Dz=hammer.state.displ()[2]
Fz=O.forces.f(hammerID)[2]
plot.addData(i=O.iter,Fz=Fz,Dz=Dz)
plot.plots={'Dz':('Fz')}
plot.plot()
O.dt=0.5*PWaveTimeStep()
O.saveTmp()
O.run()
#plot.saveDataTxt(/home/zg/scriptf/respentry1.dat)
print os.path.abspath("/home/zg/scriptf/representary1.dat")
The last line is what I have to figure out in order to save the required data.
I, however, do not see any data file by the name "representary1" at the
mentioned location. The terminal displays the following message:
TCP python prompt on localhost:9003, auth cookie `ssdeyc'
XMLRPC info provider on http://localhost:21003
Running script pentry1.py
No suitable packing in database found, running PERIODIC compression

False to get rid of this warning (your code will break in the future, however).
The returned SpherePack object can be added to the simulation using
SpherePack.toSimulation()
