[Yade-users] [Question #688370]: Two concentric cylinders but subtracting out the inner cylinder
New question #688370 on Yade:
https://answers.launchpad.net/yade/+question/688370
I am still having trouble filling in the outer cylinder while leaving inner
cylinder empty. I searched the Yade book for usage in predicates but I do not
understand how to implement this in my code (specifically Pages 50 and 51 using
Boolean algebra to deduct the inner volume from the outer volume leaving an
image similar to Image 4.4 but instead of a cylinder-shaped void in a box, I
want to have a cylinder -shaped void inside a larger cylinder. I am pretty
basic at this and any direction would be greatly appreciated!
Here is the code they gave in the Yade manual...
pred=pack.inAlignedBox((-2,-2,-2),(2,2,2))-pack.inCylinder((0,-2,0),(0,2,0),1)
spheres=pack.randomDensePack(pred,spheresInCell=2000,radius=.1,rRelFuzz=.4)
Now the problem I have is how to correctly format my Cylinder_In and
Cylinder_Out to allow for the above code to work?
from yade import pack, qt, export
cylinder_outer=O.bodies.append(geom.facetCylinder(center=(0,0,125),radius=70,height=200,segmentsNumber=20,wallMask=7,closeGap=True))
cylinder_inner=O.bodies.append(geom.facetCylinder(center=(0,0,125),radius=30,height=200,segmentsNumber=20,wallMask=7,closeGap=True))
sp=pack.SpherePack()

Hello,
I am using Ubuntu 18.04, and Yade 2019-08-08.git-775ae74
I have my code done based on [1] and somewhere at the middle of code I want to
get the values of maximum and minimum radius of the packing. I used the
following commands based on the YADE documentation:
RRmax=max([b.shape.rMax for b in O.bodies])
RRmin=min([b.shape.rMin for b in O.bodies])
print('Maximum Radius',RRmax)
print('Minimum Radius',RRmin)
And got the following error:

Jan Stránský proposed the following answer:
Hello,
> how to use plt.plot in Yade?
the same way as in any other python script
> My main problem with plot.plot is I cannot make multiple figures for
multiple plots (not subplots).
see [1]. a MWE:
###
from yade import plot
plot.addData(a=1,b=2,c=3)
plot.addData(a=2,b=3,c=1)
plot.plots = {
"a":"b",
"b": ("a","c"),
"a ": ("b",None,"c"),
}
plot.plot()
###
> File "test.py", line 295, in
next time please post complete script, here we have no idea why e22 is
not defined or what could be wrong
> as these variables are defined in a function(addplot history
function).
if you mean something like
plot.addData(e22=something)
then please note that e22 is NOT a variable nor variable name, merely parameter
name for addData function.
However, what is passed to plot.addData is stored in plot.data dictionary, so
you can access it as
e22 = plot.data["e22"]
cheers
