mvee Senior Member Vaze Join Date: Jun 2009 Posts: 172 Rep Power: 16	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
