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)). current density=-diff*(grad(potential)). with the above two equations, we can conclude that "Specified flux=current density", is it right? |

Hi dear, I encountered the same problem as yours.
How did you set the specified flux for your potential by UDF? |
