Magneto-hydrodynamic (MHD)

  Dear All
  
  I'm trying to apply a constant magnetic field on a closed-loop cycle, and I have good results without magnetic field. Applying magnetic field must affect on the mass flow rate, therefore the velocity must decrease.
  
  The problem is:
  There is no effect on the velocity when I apply the magnetic field at the right and left walls of the loop (x-direction).
  
  I think I have a problem with applying magnetic field in fluent, is there any tutorial that helps me to understand the concept of MHD? , or may you help me here, if you worked on that before?
  
  Note: I've used the manual when I applied MHD, so I need your experience with MHD.
  
  Regards,
  
  Thanks a lot

  Can you check the fluid is picking up the field: ie what causes the fluid to see the field? It's not a model that Amine & I have used so we may be of limited help on this one.

  Thank you for replying! appreciate it.
  
  yes, you're right. The contours of the field have been appeared but that didn't affect the fluid. I don't know why the fluid did not pick the magnetic field so far, so I need your help about how can I say to fluent: "The magnetic field must affect the fluid flow".
  
  plz see an attached pic if I have to change anything with,
