Giovanni Lorenzon is still having a problem:
Hi Bruno,
Thank you very much for your answer.
I tried with that command, but I couldn't make it work. I thought that maybe
the problem was related to the fact that the pressing body is a facet, but I am
not sure about that.
The related code that I used was:
#
press = geom.facetCylinder((0,0,.03), .01, .001, segmentsNumber=30, wallMask=7)
idPress = O.bodies.append(press)
O.engines=[
[...code related to other purposes...],
PyRunner(command='addPlotData()', iterPeriod=100),
]
def addPlotData():
plot.addData(
[...code related to other purposes...],
force=O.forces.f(idPress)
)
#
And each time the command 'addPlotData' was called, YADE gave me the
following error message:
"ArgumentError: Python argument types in
ForceContainer.f(ForceContainer, list)
did not match C++ signature:
f(pyForceContainer {lvalue}, long id, bool sync=False)"
Anyway, even solving this error, I'm concerned with the very output of
the command: wouldn't it give me the amount of all the forces acting on
the body, would it? Thus both shear and normal stresses I guess, right?
That wouldn't actually be what I was looking for, since I need to define
the stopping condition according to the normal stress only.
I also found the command 'forcesOnPlane'/'forcesOnCoordPlane', but also this
one computes both shear and normal stresses.
Therefore my worries about which strategy I should adopt.
Thanks again,
Giovanni Lorenzon

Question #663965 on Yade changed: https://answers.launchpad.net/yade/+question/663965 Status: Open => Answered Bruno Chareyre proposed the following answer: Hi Giovanni, If what you need is the total force on a particular object then it should be enough to check O.forces.f(bodyId). Would it answer your question?

Re: [Yade-users] [Question #663965]: Tracking interaction forces on a surface
Question #663965 on Yade changed: https://answers.launchpad.net/yade/+question/663965 Description changed to: Hi everybody, thanks again for the amazing support that you provide on this platform. I would like to ask for some suggestions about a project I'm working on. I'm trying to replicate a real-life compaction process in a cylindrical cavity, and I would like to stop the compaction when some specific normal strain value is reached. I am trying to build an actual cylinder to which impose a certain velocity to, and to stop its path towards the sample when a fixed strain is registered upon the contact surface. The problem is that I am having difficulties in finding an appropriate way to measure the interaction between the particles and the pressing object's surface, in order to define the stopping condition for the compaction process. Until now I was using the uniax.py example from GitHub, but its execution is way too demanding for the number of particles I'm wishing to simulate. Any suggestion about which strategy would best fit my purpose? Thank you very much for your help!
