Question #253425 on Yade changed: https://answers.launchpad.net/yade/+question/253425
Bruno Chareyre proposed the following answer: "stress" recorder averages for each body the normal stress or shear stress of all interactions associated to this body. It needs to assign a cross section to each interaction, which is somehow arbitrary. The mechanical meaning is not clear. I think we should remove this feature and replace it with bstresses. > convolution of particle stress with a weight function Say you define a weight function W (e.g. a normal distribution) centered on (x,y,z), such that W(X,Y,Z) vanish far away from (x,y,z). The convolution of W with stress reads sum(W(b.pos-(x,y,z)) * stress[b.id])/sum(W(b.pos-(x,y,z)) and gives the stress in particles sufficiently close to (x,y,z). That way you get a local average defined everywhere by changing x,y,z.
