Uncrossable Chains of Blobs

Briels and collaborators [136-139] proposed a coarse-graining scheme wherein chains are subdivided into a number of subchains of equal length the center-of-mass of each subchain is taken as the position of a corresponding mesoscopic particle 

In order to describe shear flow effects in a velocity field of the from v (r) = yvy, Kindt and Briels [136] proposed the use of the SLLOD algorithm [140]. Starting with a Langevin equation, such a method results in the following expression for the blob dynamics
