Abstrakt v dalším jazyce:	EOF-Library, our open-source efficient coupler for Elmer FEM and OpenFOAM, is successfully validated against COMSOL Multiphysics, a commercial simulation package. We inform about discrepancies between our results and data from a series of research papers in the field. Simulations wherein microwaves are supplied to a water domain through a rectangular waveguide are used as benchmarks. The cases are conjugate problems involving fluid property dependence on temperature, microwave propagation and absorption, Marangoni effect and buoyancy-driven flow. We also report surface flow instabilities arising during prolonged microwave heating.
