Maryam-A is on a distinguished road
Thank you for response.
I wanted to return gradient of UDS ( scalar is volume fraction of nanoparticle in my case) as boundary value.
by simplifying transport equation , my boundary condition on the wall is:

d(phi)/dx=-(DT/DB)*(dT/dx)

that UDS(c,t,0) is phi. As you see I wanted to return derivative not value of phi.

I'm beginner at UDF .
Could you please give me some advise to use a proper function?
