how to manipulate the external force in Navier Stokes Equation?

Please login with a confirmed email address before reporting spam

Hi, I'm currently trying to manipulate the external force in Navier Stokes Equation and having some trouble. In my model there are two identical permanent magnets that are attached to 2 rotors. in between the rotors there is a tube filled with ferrofluid. I'm trying to make fluid flow using the magnetic force between two magnets but I can't figure out how to use the force I calculated from the Magnetic Fields. No Current physics into Laminar Flow physics. Is there a way to manipulate the external force in the equation?

Any help would be much appreciated! Thank you.
