In this work, custom codes were developed for HPC-based magnetohydrodynamics (MHD) simulations, enabling the design of a dedicated electromagnetic stirrer (EMS) for the electric arc furnaces (EAF). The fluid-dynamics of liquid steel within the EAF under the effect of electromagnetic stirring has been studied under different simulation parameters. We performed parallel simulations using an OpenFOAM solver and other related programs on IBM-FERMI (a PRACE Tier-0 system) at CINECA, Italy. We realized performance analysis for the current sequential version and updated parallel versions of the code via extensive simulations. We present and discuss the results of the scalability analysis of the specific codes using two different domain decomposition methods including simple and hierarchic.
