Different Terms in Different UDS
 

Hi Everybody

I'm programing two UDS (User - Defined Scalars) and I would like to know if it is possible to have two different Unsteady Terms as well as two different Advective and Diffusivity terms (one for each scalar)and how can I specify them, for the right scalar.

Really need help. With my best regards:

In those macros FLUENT passes a variable, i, to your udf. This integer represents the uds equation. The first uds is i = 0 and the second is i = 1 and so on. Include a logical expression for i in your marco to define the correct expression for each uds.

for example

if (i == 0)

uds-0 expresseion

else if (i == 1)

uds-1 expression
