Hi All,
So in a follow up to my post about creating an actuator disk in Fluent, I'm trying to create an interior face boundary in FLUENT and I am not sure how. First off is it even possible to create such a thing? Basically what I want is just a face at which I can assign a given pressure value. Is that something FLUENT can handle, or is it beyond FLUENT's capabilities? If anyone could point me to any resources on this topic I would very much appreciate it. |

It's probably easier to go back to the mesh generator and create your "interior" boundary.
It's very tricky to do inside Fluent. Within Fluent, you would need to part the domain into separate domains. |

It is possible and relatively simple. What you need to do is to identify the adequate variable to define the region that you want to modify as an interior boundary. For example, if the region is located ten cells from a boundary you can mark the region using the cell distance variable. Or if it is a cylindrical, hexahedral or spherical region you can use the mark region options available in Fluent. Once you mark the region you can manipulate the mesh with respect to the marked region. For example, separate the cell faces.
After you have separated the faces you can specify the region as a fixed value face zone, and impose the value of the desired variable. |

Exactly a quick way to access cell faces by marking the specified region in fluent. And other way is to define during mesh generation.

I understand it is been a while. But I am stuck with the same thing. I have an internal face which I need to make ansys meshing realise that so FLUENT can read it.
in 2D case i use to draw a line and fill it using the fill option, which works perfectly but in 3D I am failing to make ansys understand the internal Face. Could someone please help? |
