Thank you also for the answers to the concrete cube's dimensions and the variation of aggregate particles. I will ask separately as a rule in the forum. My cases are the following: I have tested the compressive strength of the concrete cube (150mmx150mm), and I will be modeling in YADE. In modeling, I will consider stress and strain periodically. I am still confused about how to determine the (xxPath, yyPath,zzPath,zxPath,xyPath), as written below. xxPath=[(465,5e-4),(934,-5e-4),(1134,10e-4)], #old yyPath=[(2,4),(7,-2),(11,0),(14,4)], zzPath=[(5,-1e7),(10,0)], zxPath=[(4,2),(14,-1),(22,0),(28,2)], xyPath=[(1,1),(2,-1),(3,1),(4,-1),(5,1)], Can you please help?

[Yade-users] [Question #690942]: Concrete cube dimension, aggregate particle and peri3dController
New question #690942 on Yade:
https://answers.launchpad.net/yade/+question/690942
Dear All,
I am new to YADE. I have studied some code from this forum. There are some of
the questions related to concrete cube testing.
1. How to determine the dimensions of the concrete cube (150x150mm) in the
modeling? In the code, there is an initial size = 1.2, but apparently, this is
not the cube dimension.
2. How to determine the variation of aggregate granules if specified;
a. 0-4mm: 40%
b. 4-8 mm: 22%
c. 8-16mm: 38%
3. How to determine the value (goal, xxPath, yyPath, zzPath, zxPath, xyPath),
I'm confused with the determination of the numbers . I have read it in YADE
Book (pg.280), but i dont understand about it.
goal=(20e-4,-6e-4,0, -2e6,3e-4,2e6)
# the prescribed path (step,value of stress/strain) can be defined in absolute
values
xxPath=[(465,5e-4),(934,-5e-4),(1134,10e-4)],
# or in relative values
yyPath=[(2,4),(7,-2),(11,0),(14,4)],
# if the goal value is 0, the absolute stress/strain values are always
considered (step values remain relative)
zzPath=[(5,-1e7),(10,0)],
# if ##Path is not explicitly defined, it is considered as linear function
between (0,0) and (nSteps,goal)
# as in yzPath and xyPath
# the relative values are really relative (zxPath gives the same - except of
the sign from goal value - result as yyPath)
zxPath=[(4,2),(14,-1),(22,0),(28,2)],
xyPath=[(1,1),(2,-1),(3,1),(4,-1),(5,1)],
Could you please help me with this?. I'm writing a thesis and paper using YADE.
