A question about UDS (user difined scalar)
 

Hi, everyone

Thanks in advance.
Now I have a urgent problem on uds, which is as follows:

I want to know how to access the uds gradient on the boundary faces,
The manual shows C_UDSI_G(c,t,i) is used to obtain the cell gradient,so how about the face gradient? If no macro is available, is there another way to solve it?

You may use F_UDSI_G insted.

Thanks,

The point is that I cannot find this macro: F_UDSI_G(f,t,i) in FLUNET manual.

Does it exist?

and how did you find this macro?

Thanks.
