I am trying to quantify the effect of magnetic fields on discrete particles under fluid flow using the DPM and MHD model. The case I'm using is a simple 2D bifurcation with 50-50 flow split. I have no problem importing my magnetic field and visualising it and the induced B field. For MHD, I make use of magnetic induction. The magnetic field is oriented in that way so that particles should flow mostly to one outlet. First I initialize both MHD and DPM, then I import my B field and run the simulations. However, when it comes to the DPM, I've defined the magnetic properties of the particles, but the magnetic field does not influence the particle trajectories. My current settings are interaction with the continuous phase, steady particle tracking and the pressure gradient force, Saffman Lift force and virtual mass force are enabled.
How can I fix this?

Can you plot the magnetic field to see if it should effect the particles. Also, check the DPM panel UDF tab to make sure the module's hooked up.

Thank you for your response. I checked my DPM panel and plotted the magnetic field. Both appear to be okay. I've added some screenshots for more context. (I've done the simulations for 3 different orientations of the magnetic field but none of them affected the particles, I've added screenshots of 1 of them)
