Hi there,

Im desperatlz trzing to model a conjugated heat tranfer problem in Fluent but i dont get the coupled wall option in the BC.

This is the problem:

I have a hot plate (solid) being surrounded by a liquid channel. The plate is a siple square extrusion in the DM. The channel has been generated with the "enclosure" feature in the DM. When I mesh all of this and import it to fluent I dont get the shadow wall thus can not choose BC "coupled". Is there something to watch in the meshing/ the design process ?? I have deleted the connectionsin the mesher.

Thanks

Mathieu

Use the Fuse Face Zones Dialog Box in Fluent (Mesh->Fuse)
in order to fuse faces between solid and liquid media.
Then the shadow wall is created automatically...

Hi There,

thanks for the answer. I found a very simple solution myself which might help other peaple:

In the DM you have to join your parts to a single part model. Just Mark all the parts and then right klick "join parts to one part".

Then Mesh all this. Now the Walls between Solid and liquid are shared. No Fluent will generate the coupled wall which you need for the conjugated heat transfer.

It is also posssible to fuse the meshes later , but I find it easyer to do it in the DM so that in the mesher you can see the quality of the fusion.

Cheers

Matt
