Multiple cell zones in FLUENT

I am trying to create multiple cell zones so that I can have different porosity in each zone. This is a 2-D asymmetric model, and I generated the mesh using Ansys's Design Modeler and Meshing tools. Right now, I can get several zones, but FLUENT is requiring that the lines between each zone has its own boundary condition (FLUENT has assigned all of these lines names that begin with "surface_"). Is there a way to remove the surfaces from the model in FLUENT? Or is there a better way to use the ANSYS tools to create a multiregion model?
Thanks for your help! |

If I understand correctly, you are just trying to get all of the zones to behave as one continuous fluid domain. Ideally, you would want to generate a conformal mesh, which you can do by making all of your zones one 'part' in Design Modeler. You can do this by selecting them and right clicking then selecting "form new part".
To connect the fluids at the interfaces, you need to merge the two surfaces at each interface (between fluid zones). To do this go to 'Mesh Interfaces' under 'Problem Setup' in the menu bar on the left. It is fairly straightforward from there. Hopefully this helps. -Zachariah |

Can anyone help me with the creation of multiple zones during meshing?
Is there a tutorial for that? |

how do i draw a 2D block capable of being split into two zones? I need to create a free surface in a tank.
thanks |

so i did exactly what you say, but what i should define this line between two fluids??as interface??or as moving wall? Thank you in advance! |

Hello Dears
I have a pipe with oil and a water droplet is in the middle of it I use of "Form New part" and solve my Boundary condition where I have a boundary for droplet as interior But there is a problem now: there is not in the mark list for marking for patching because it is interior type now it gose to control switch how can I patch the interior droplet for define only one phase (water) for it ? regard |

1. draw the chamber/channel in design modeler without the droplet 2. mesh it 3. in fluent, adapt the region you want to put a droplet and mark it 4. patch the adapted region to the secondary phase(i.e. water) |

hi Dear kevinxichan
I don't want to use of mark regine in fluent because I want to use of different tyes of shape of droplet like elilp or other nontipically shape so I think it is not possible with this switch so I should model it with other software and import to fluent regard |

Dear kevinxichan
I try your suggestion I marked and patched the second phase (water droplet) before runing and calculating , I only can see the regine patched with management register window but it can not show the phases in contour when i choose phases when i click on display button in contour window Question : must I see the regin patched before calculation ? how can check the patch before calculation ? why can not I see in contour now ? regard |

Have you solved your problem yet? I'm sorry that I haven't checked this forum for half a year.

Where exactly do you do the merging of two surfaces? I cant seem to find the problem setup menu nor the mesh interfaces option. There is only solution setup in fluent. Thank you in advance! |
