subha confirmed that the question is solved:
Thanks Klaus!
It worked when executed with yade "filename.py".
Just wondering what is the difference when the script is run using
execfile("filename.py") and yade "filename.py" because the former one
works fine when no function is added.
Just another comment, I wanted to save both snapshots and data at the
same time using PyRunner and for that purpose, I added the following
lines to the script:
O.engines+=[PyRunner(iterPeriod=100,command='saveImg()'),
PyRunner(iterPeriod=5,command='plotAddData()')]
and defined the image saving function as:
def saveImg():
qt.SnapshotEngine(fileBase='/home/subhasish/YADE/tutorials/image/img-')
The geometry is shown in runtime as before:
#show geometry:
v=qt.View(); v.axes=True
v.viewDir=Vector3(0,1,-.05)
v.eyePosition=Vector3(0,-5,.5)
The script, however, does not save any runtime image.
Any suggestion will be appreciated.
Regards,
Subha

subha is still having a problem:
Hi Klaus,
Thanks again to have a look at this. Sadly, the problem still persists.
The outcome is:
ameError Traceback (most recent call last)
/usr/bin/yade in ()
NameError: name 'plotAddData' is not defined
and no data were written in the "txt" file.
I copy-pasted the modified code as it is and executed using both "yade"
(ver. 1.07) and "yadedaily" (ver. 1.20) through the command
execfile('filename.py').
Since you checked the code running at your end, I'm thinking about any
missing "yade" component during installation. What would be your thought
on this?
Many thanks.
Subha

[Yade-users] [Question #293179]: 'Name error' while calling function
New question #293179 on Yade:
https://answers.launchpad.net/yade/+question/293179
Hi All,
I am simulating a particle impact on a flat surface and would like to track the
position and kinetic energy of the particle.
I am using yade 1.07 version on Ubuntu 14.04 LTS.
I encountered a problem with the "PyRunner" in my script while executing a
function meant for saving data after every N iteration.
The script is given below:
from yade import qt
from yade import plot,pack,geom
#define material properties:
rho = 2500 #density
fric = 0.5 #friction coefficient
fric_angle = atan(fric) #friction angle in radian
stiff_n = 1e8
stiff_s = 1e8
c_n = 0.1 #normal viscous damping
c_s = 0.1 #shear viscous damping
l_d = 0.2 #local damping
#define a material:
Mat = O.materials.append(ViscElMat(kn=stiff_n, ks=stiff_s, \
cn=c_n, cs=c_s, density=rho, frictionAngle=fric_angle))
#create a sphere:
b1 = utils.sphere(center=(0,0.0,1),radius=0.05,fixed=False,material=Mat)
O.bodies.append(b1)
#O.bodies.append(utils.sphere(center=(0,0,1), radius=0.05, material=Mat))
#create a plane facet:
O.bodies.append(geom.facetBox(center=(0,0,0), extents=(0.5,0.5,0), fixed=True,
material=MyMaterial))
#define engines:
O.engines=[
ForceResetter(),
InsertionSortCollider([Bo1_Sphere_Aabb(),Bo1_Facet_Aabb()]), #Axis-aligned
bounding box
InteractionLoop(
[Ig2_Sphere_Sphere_ScGeom6D(),Ig2_Facet_Sphere_ScGeom()], #Interaction
geometry
[Ip2_ViscElMat_ViscElMat_ViscElPhys()], #Interaction physics
[Law2_ScGeom_ViscElPhys_Basic()], #Contact law
),
GravityEngine(gravity=(0,0,-9.81)),
NewtonIntegrator(damping=l_d),
qt.SnapshotEngine(fileBase='/home/subhasish/YADE/tutorials/image/',label='snapper',iterPeriod=100),
PyRunner(iterPeriod=5,command='plotAddData()')
]
O.run(5)
#show geometry:
v=qt.View(); v.axes=True
v.viewDir=Vector3(0,1,-.05)
v.eyePosition=Vector3(0,-5,.5)
O.dt = 1e-4
#O.dt=.5*utils.PWaveTimeStep()
def plotAddData():
pos = b1.state.pos
Intrs = len( b1.intrs())
plot.addData(i=O.iter,t=O.time,x=pos[0], y=pos[1], z=pos[2],
Ek=utils.kineticEnergy(), nIntrs=nIntrs)
plot.saveDataTxt('file2.txt.bz2')
The error appeared on the terminal as "NameError: name 'plotAddDatan' is not
defined". I came across similar problem in this forum but none seems to work.
Any help would be appreciated.
Regards,
Subha
