One of our main specialities is MHD. Because numerical simulation tools for industrial MHD are rare,  unstable or slow, we have developed a tool EOF-Library that has become a standard for industrial MHD modeling. It is open-source code that couples OpenFOAM and Elmer FEM, and can be run on massively parallel computers.

Many metallurgical manufacturing applications, e.g., electromagnetic levitation melting or stirring, have turbulent flows. Typically, isotropic turbulence models like kEpsilon or kOmegaSST are implemented because of their lower computational costs, but averaging process inherently introduces dampening of perturbations and instabilities. The fine-scale flow details are lost and the flow that might appear steady-state in the simulation, will be transient and chaotic in experiments. To make simulation models real, one must, for instance, use the Large Eddy Simulation (LES) method, which treats turbulence in a fully three-dimensional manner, even if they possess exploitable symmetries. The result is seen in the video above where levitating metal starts rotating around its central axis despite the setup being symmetrical against the vertical axis. Instabilities are highly undesirable in such large application like aluminium smelting.
