We use a mesoscale simulation to measure the strength of the velocity flux needed to push a polymer into a narrow channel. We find excellent agreement with the prediction by T. Sakaue, E. Raphaël, P.G. de Gennes and F. Brochard-Wyart, Europhys. Lett., 2009, 72, 83, based on a de Gennes blob model of the polymer, that the critical velocity flux for translocation depends linearly on the temperature, but is independent of the length of the polymer chain or the width of the channel.
