Hi

I am solving a scalar equation for one variable. The source term of which is having gradient term like \frac{\partial{u}}{\partial{x}}.
'u' is not axial velocity but it is obtained through algebraic equation which is again the function of x.
I need to discretize the equation through UDF. How can i do this?

Any comment.

Thank you
Mvee
