Using the Thin Wall Boundary Condition with the MHD module in FLUENT

  I've been trying to model simple MHD flow through a duct in FLUENT. I have a simple rectangular, 3D geometry, and was trying to apply the thin wall condition to two of the walls. The other two I left as insulating. When I try to set the thin wall condition and set a thickness for the wall, however, FLUENT automatically resets it to zero. I have tried to use the text commands instead, and while it does not reset the thickness to zero, it still gives an "Invalid potential field" error when I go to solve. I haven't seen anything in the documentation or previous issue people have had that has helped me resolve this issue. Thank you!

  HI adix, i had the same problem.
  You need to define the wall thickness at the thermall tab when you define the boundary conditions like if you haven't activated the MHD module.
  After that the wall thickness at the MHD bounday conditions should appear.
