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
