RANS simulation of MHD channel flow

I would like to conduct a simulation of Magnetohydrodynamic (MHD) turbulent channel flow (electrically conducting fluid flowing in a channel under the influence of magnetic field). My case pertains low-magnetic reynolds number flow. Since i know there is no MHD module integrated with star-ccm+, I would like to utilize user written function feature in star-ccm+. However, I am beginner in star-ccm+ and I am not sure how the UDF works in star-ccm+. As there is an additional Lorentz force term in the momentum equation, i need to calculate the electric potential which is used for lorentz force calculation.
I will appreciate if anyone who is experience with MHD simulation can shed some insight.

I don't have much experience with MHD, but I believe you could use a field function to define the strength of a momentum source that encompasses the channel where the magnetic field is acting. I've used a similar approach to achieve an "actuator disk" style representation of a propeller.
