Resumen:
The curvature calculation in the context of the Volume of Fluid method is a crucial step in orderto accurately solve multiphase problems with dominant surface-tension forces. Most of techniques failin obtaining mesh convergence, even increasing the parasitical currents due to wrong calculated curva-tures. This work presents the application of the height functions technique to problems discretized withnon-structured meshes. The implementation is tested showing second order convergence rate for theinterphase normals and first convergence rate for the curvatures. Additional tests are presented solvingmultiphase flow problems by the Volume of Fluid method.
