| We propose a microscopic model for solutions of wormlike micelles and report results from NonEquilibrium Molecular Dynamics ( NEMD ) computer simulations under shear flow. Our model ('FENE-C') introduces the concept of scission-recombination and is an extension of a recent model established by one of us (M.~Kroger) for polymer melts. In this first study our interest is focused on the relevance of the microscopic model by comparing the results of the simulations with the predictions of mesoscopic theories. The simulated behavior shows an exponential distribution for the micellar length and an exponential dependence of the average length against the scission energy at equilibrium. These results are in accordance with those calculated from Cates mesoscopic theory. Simulations results of shear effect on the size distribution and on the size of the micelles are also reported and discussed.
