We present an advected-field model of fluid interfaces at low Reynolds numbers and apply it to the fundamental problem of drop dynamics in an external flow. We focus on the ability of the numerical method to account for topology changes such as breakup, and compare the results obtained with this method to experimental data and theoretical predictions.
