Hi All,

Anybody working on carona discharge and electric field UDF?. Please help me in writing UDF.
I have a probelm in setting ion density and voltage at the electrode.

John

Hi Amir,

Nothing yet, but i have understood that i have to couple Fortran or MATLAB with Fluent to do that.
Do you have any clue??

You can always use a User Defined Scalar to solve for the potential field, with the charge density as a source term. If the charge density varies is space, then you'll need to write down a transport equation for it, and solve it as a user defined scalar too.
