Dear Selvam,

What kind of electromagnetic fluid flow simulation are interested in? Is it the Lorentz force that you want to put in?

There is a beta feature within ANSYS CFX 10.0 to address problems like magneto-hydrodynamics. You should contact your service representative and request information about it.

Good luck, Opaque.

othrewise, you include a general body force by first creating a subdomain where you want your force to be applied, and in the subdomain dialog select sources. There you can specify a General Momentum Source.

There are some details about this in CFX help, I think.. Do a search for 'Momentum Sources'
