Mesh for conjugate heat transfer
I have made a 2D geometry and have meshed it in ANSYS 12.0
When i export the mesh to Fluent, there is no shadow wall at the solid-fluid interface. Hence, i do not get the 'couple' option in wall boundary condition ( as i am supposed to find). Can anyone tell me the reason why this is so? thanks in advance! regards Hassaan |
Check īthe connectivity of the faces. If you are a GAMBIT user, the color of the line between two faces should be pink.

Multi-body part...
I assume you are using ANSYS Meshing in Workbench...
If you have separate parts, it will mesh them one at a time and the edges won't really be connected. You need to combine these into a multi-body part so they will be meshed together... There are other posts about how to do this, or you could check the help... |

But now i cant seem to mesh the tube bundle. A straight pipe without bends is meshed easily but one with bends gives an error. Is there a different method to do this? Help will be greatly appreciated Thanks! :) |
Have you specified the mesh method? Perhaps "automatic" won't generate a swept mesh, but specifying swept, along with a source and target surface will do the trick...
Or you could try "MultiZone". |

conjugate heat transfer
Hi, I work model contain fluid and solid wall when I run in fluent the heat don't transfer from wall (hot) to fluid (cold) in which I mesh each one separately. what wrong ?

Connection between two region

I know this thread is old but i need your advice! Could you solve your problem? I have same problem! I meshed two region in gambit and when i run my case no heat flux cross the boundary. And just one region have rise in temperature. Any idea? Thanks in advance |

Thanks for your kind response What kind of software should i creat interface? I am working with gambit And i defined internal boundary condition between common face. When i use hex grid for both region it is ok with internal bondary condition for common face but when i use tri mesh it doesnt couple! Any idea is welcome Best regards |
