Although there have been extensive works in the past that have presented approaches to resolve these so called Marangoni flows at the phase boundaries, the question of how to efficiently resolve the interface in a universal and conservative manner remains largely open in comparison. Such problems are of high practical relevance in many manufacturing processes, especially in the microfluidic regime where capillary effects dominate the local force equilibria. In this work, we present a freely available numerical solver based on the Finite Volume Method that is able to resolve arbitrarily complex, incompressible multiphase systems with the mentioned physics at phase boundaries. An efficient solution with respect to the number of degrees of freedom can be obtained by either using high order WENO stencils or by employing adaptive cell refinement. We demonstrate the capabilities of the solver by investigating a model benchmark case as well as a single track laser melting process that is highly relevant within laser additive manufacturing.  \nIndex Terms—finite volume method, adaptive refinement, marangoni flow, open source software  \nI. INTRODUCTION  \nAccurate modelling of complex physics has received considerable attention within the last two decades. This can mostly be attributed to the fact that an increased understanding of the phenomena relevant for manufacturing directly leads to more finely tuned or even new processes that tend to increase output quality.  \nTwo such examples that shall serve as a guideline for this work are microfluidic applications and additive manufacturing of metals. Both groups of processes are characterized by complex flow phenomena that involve several physical phenomena on a microscopic scale [1], [2] . The fact that those effects tend to have fast dynamics further complicates the analysis [3] . This leads to an increased amount of empirical effort necessary to capture and quantify the flow patterns involved.  \nHence, simulation has become an important alternative to extensive experimental research.
