  An open-source library called EOF which provides efficient two-way coupling
between the finite element multi-physics simulation software Elmer and
computational fluid dynamics software OpenFOAM is presented. Library controls
interpolation and communication of fields between two codes. The main focus of
this code is industrial magnetohydrodynamics with free surface, but it can be
extended to other 2D and 3D multi-physics problems. Simulation results for 2D
axisymmetric problem of conductive fluid with free surface surrounded by
alternate electromagnetic field created by inductor are compared with analogous
simulation results made by another author.
