Numerical simulation tools for industrial magnetohydrodynamics (MHD) are rare, especially open-source codes that can be run on massively parallel computers.

The initial application for the EOF-Library was magnetohydrodynamics (MHD) with free surface modelling of various industrial applications. MHD problems involve coupled electromagnetics and fluid dynamics therefore we chose to couple two open-source packages – each one responsible for particular physics models. Among many FEM software packages, Elmer FEM was chosen for electromagnetics and OpenFOAM for fluid dynamics .

The Message Passing Interface (MPI) is used for data transfer between software, it results in low latency, high data bandwidth and parallel scalability.

Here we present simulation cases that illustrate application of EOF-Library for 3D MHD problems.

Levitation melting of liquid metal

The problem involves alternating electromagnetic fields and conducting fluids with a free surface, we perform a 3D numerical simulation of levitating liquid metal in an alternating electromagnetic field and compared our results with the results of similar numerical simulations and experiment. 

Surface wave generation

We optimized new silicon recycling technology. Surface waves are generated using low frequency electromagnetic field.
