Does FLUENT permit to define dS2/dt=0
Hi fluent expert

I have used the UDS for defining two partial differential equation,but in one of them the derivative of variable(S1) with respect to time is zero.In this case if you select UDS menu you will see that we have three options.If you select default case in both equation, time derivative will appear,so you should use UDF option. I will be glad if some one say me that how I can omit the time derivative from one equation.

Thanks in addvance
