  6. Simulations were performed by a sharp-interface moving mesh finite element method using the framework pyoomph [10]. The weak formulation is a three-dimensional version of the method described in the supplementary information of Ref. [11] using a quarter droplet with symmetry boundaries and >600000 degrees of freedom.
