Simulations of gravity-induced trapping of a deformable drop in a three-dimensional constriction

► An algorithm for a drop to approach trapped state in a 3D constriction is developed. ► The algorithm is far more efficient than the scheme with true temporal dynamics. ► The wetted areas with solid boundary are not prescribed but found from the solution. ► Critical Bond numbers for squeezing are studied for different 3D constriction types.
