nobody is still having a problem:
Hi Jan,
In your MWE, you use (b.mystress = stresses[b.id] ), this command and then
export it.
while here[1]. the micro-stress part mentioned that first we need to get
the per-particle stress given by bodyStressTensors.
here in my opinion, what you've done is just to get the per-particle
stress.
After that, we need to use this command: stress =
s[b.id]*4.*pi/3.*b.shape.radius**3/TW.volume(b.id). as [1] mentioned we
need to re-normalize it in order to obtain the micro-stress.
overall, in my opinion, I think this is (stresses[b.id] ) to get the
per-particle stress.
stress = s[b.id]*4.*pi/3.*b.shape.radius**3/TW.volume(b.id) this is to get the
micro-stress.
I don't know my understanding is right or not.
if your opinion is right, which means per-particle stress is the same as
the micro-stress filed??
can you help me to understand this more thoroughly?
best,
yong
