Hi. THis is a very open-ended question. Start off by searching the forum for “electr” and “magnetic”

Magnetic field force

How can i insert magnetic field force code into mfix? thank you very much!

How to model electrostatic precipitation process in MFiX?

Greetings, After attending the MFS workshop this past summer, I am tempting to use MFiX for my study. I study the process of electrostatic precipitation and would like to know if MFiX can model such process. In general, I need to solve the Maxwell’s equation for electric field, fully coupled with a charge transport equation and then a turbulent fluid flow field (k-epsilon) is solved along with the Lagrangian particle trajectories. The flow condition is dilute, so two-way coupling between the p…

How to add new force in CFD-DEM model

Hi all, In CFD-DEM model, I was trying to add more interaction forces of particle-particle and particle-wall on top of the built-in van der Waals (especially the electrostatic force to complete DLVO theory), I understand the main source code I need to modify is calc_force_dem.f, but I’m wondering how can I modify the corresponding udf files (or which one should I modify) to hook the implementation? Anybody who had related experience has any suggestions? Thanks.
