Hello,
Now, I am trying to scalar transport simulation.
I impose "1.0" of "Prescribed Value" for inlet condition, and "0.0 (zero)" of "Prescribed (outgoing) flux" for outlet condition.
Here I am wondering that what is "Prescribed (outgoing) flux" for outlet condition.
If I define zero flux for "species for backflow" at outlet, is outlet boundary equal to free outlet condition (or wall condition)?
I just want scalar to come from inlet and go out from outlet boundary. So it is just no gradient for scalar concentration.
Best regards,
Tsubasa
What is "outgoing flux" for species?

Hello,
I think the value given in the GUI is used only if the fluid comes back in the outlet (so should be more logical for free inlet/outlet than outlet). It may also affect the diffusive term. You can simply leave it at 0.
