3.4 MHD Interaction with Discrete Phase Model

In discrete phase modelling, the Lorentz force acting on charged particles is introduced through the user function DEFINE_DPM_BODY_FORCE(mhd_dpm_force, ...). User function DEFINE_DPM_SOURCE(mhd_dpm_source, ...) is used to update the volume fraction of the discrete phase inside a fluid cell and the volume-weighted electric conductivity of the discrete phase.
