An arbitrary Lagrangian Eulerian (ALE) interface tracking method is applied to multiphase flows involving wetting phenomena. The method is implemented in OpenFOAM and validated for the static shape of a drop deformed by gravity influence. Results for a constant contact angle model are compared to approximate analytic solutions for the limiting cases of vanishing or infinite Eötvös numbers. Results between the two limiting cases are compared to numerical results from literature.
