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.

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

Hi Zachariah,
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!
