Abstraet-An appraisal of the rheological model proposed in Part I is presented. The experimental data on six fluids (four polymer solutions. one soap solution and one polymer melt) are used to test the model in various flow situations: steady simple shearing; oscillatory, small-amplitude simple shea

## Abstract **Summary:** Using molecular dynamics simulations, we determine the linear and nonlinear viscoelastic properties of a model polymer melt in the unentangled regime. Several approaches are compared for the computation of linear moduli and viscosity, including Green‐Kubo and nonequilibrium
