Porous_jump in fluent
Excuse me,
Hello everybody, I have one question. Why I can't find porous_jump in fluent boundary conditions ? Thank you for your help. |
Hello Erlanda,
it means that for this boundary you can't select this boundary condition. Can you post some pictures of your system? Regards |

Hi Bionico, thank's for your help.
This is my picture when Iam running it with ansys fluent. |
Are you selecting an internal face? Porous jump is an internal boundary condition, so it can't be used for external faces where inlet/outlet conditions can be applied.
|
Yes Iam selecting an internal face when I build geometry in meshing process, but When Iam processing in fluent boundary condition, I can't find porous jump in optional.
So, what I must to do ? Thank you for your help |
Hi Erlanda,
I can open your mesh: which boundary condition do you want to define as porous-jump? regards |
Hi, Bionico
The porous_jump in the bottom side of second volume (inlet volume). Thank you |
Hello Erlanda,
inlet boundary condition can't be defined as porous-jump: it isn't an interior face. About your mesh, I have a doubt when I display it: are the two volumes overlapping? Regards |
Hi Bionico.
No, the two volume aren't overlapping. The second volume inside of the first volume. After that, I have one question. In above side of second volume, I definied boundary condition was outflow, and I had some problem with outflow and pressure outlet (boundary condition in above side of first volume). Why were the both of them domain, and didn't definition ? Thank you for your help. |
Hi Erlanda,
What you used as mesher? I think you made some mistakes in meshing because I see two disconnected volumes (as I said before I see the interior mesh of the bigger volume overlapping the smaller one), so inlet isn't an interior face: I suggest using a conformal mesh. Maybe also the problem with outlet boundary is the same. Regards |
Hi Bionico.
How can I find conformal mesh menu ? Thank you. |
I usually use DesignModeler + Meshing as pre-processing softwares: in order to obtain a conformal mesh you have to put all the bodies in the same Part. If you create different part, you'll obtain a non-conformal mesh.
If it's not a problem, post your geometry (in Parasolid or Step format). Regards |
Hi Bionico.
Anyway I use Gambit software for pre-processing. Is it possible to find conformal mesh in Gambit ? Thank you. |
I used Gambit in the past, but I don't remember how to create conformal mesh, unfortunately :(
Check on the Manuals. Regards |
Oh, okay.
Thank you Bionico. I will try it. |
