question about uds
hello,everyone. I am new to Fluent. Here I have a question.
I have added an UDS(potential) . But I confused when I imposed the BC. There are two type of BC for UDS. One is "Specified flux",and the other is "Specified value".
And what I know is that "Specified flux" means "-diff*(grad(potential))".
Here is my question!
As for insulating wall, we should choose the BC with "Specified flux" equal to zero. Is it right?
Another question is that I imposed a constant current on another boundary, and this time how should I set the value of "Specified flux"?
Additional, Specified flux=-diff*(grad(potential)).
with the above two equations,
we can conclude that "Specified flux=current density", is it right?
Is there anyone who can help me or give me some suggestion?
