(a) Distribution of the polymer monomer along the radial direction of the cylinder channel with identical action radius R = 3, monomer number N = 100, but with different chain stiffness parameter b. (b) Results with identical chain stiffness parameter b = 200, but with different cylinder radius R = 2, 3, and 4 from the top to the bottom. Each plot has three curves corresponding to three different chain monomer numbers N = 50, 100, and 200, respectively.
