Discretization through UDF

mvee · March 7, 2013, 03:40

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 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

Hi

'u' is not the velocity and cann't be obtained with ready made (C_U_G) macros.

I need to discretize it explicitly.

Thank you
